one in some time. What say you Texas Cavers?

I use GGG as well, based on it being the majority vote after asking multiple 
rescue and cave folks.  It has been good for me.  Have not done butt loops yet 
but would be nice, mostly use it for rescue stuff so I keep it pretty minimal.

I'll suggest the GGG, too.

As for butt loops. I just used some 3 mm accessory cord. I ran the cord through the loop at the back of the waist strap and then tied off to each leg loop. That has worked for years--cheap, easy, and simple.

People keep mentioning these butt loops, so I have to ask... Why doesn't the 
harness come with them in the first place? Would seem like poor design to me...

I added leg padding and a padded/adjustable butt loop to my GGG harness, to
make the perfect harness for me.

The MTDE Amazonia is my favorite. Comfortable, fairly compact, rugged,
and the lowest attachment point of any harness I've tried, which is
great for frogging. I don't know if anybody's importing it these
days--with international shipping and exchange rates it might not
quite fit <$100. I think I got mine from starlessriver.com in the UK.
I also used a GGG harness for a few years and liked it fine without a
butt loop.

Austin has emissions testing also, so I’m out as a buyer.

That's similar to my 1988 'burb 3/4 ton 4x4.  Mine was a RV Special, special 
ordered from the factory with all heavy duty options.  Ever two years the 
previous owner (owned a construction company) bought his wife a new caddy and 
bought custom ordered a new suburban for himself.  Big car lots consider any 
trade in with over 70,000 miles as a high mileage vehicle and try to get rid of 
them as soon a possible.  This one had 73,000 miles on it and a winch, nobody 
wanted it with the 8,000 lb Warren wench.  Got a great deal on it, drove it 
until it had 170,000+ miles and sold it to Ed Goff (first truck I ever owned I 
was willing to sell to someone I knew their name.

Know of anyone out there that might be interested? This is definitely a great 
bargain and One Big Tough Truck.  I have been driving it and I think Dan has 
honestly advertised it.

I depends on how they require it, Jim. This is a 25 year old vehicle. a 1988.   
What are your local emission testing requirements for something that age?

If it's 25 years or older, it doesn't have to pass emissions testing.

Thanks, Logan.  I thought that was the case, but was not sure.  In Colorado the 
testing requirements are quite variable from one municipality/area to another . 
  The Front Range is especially strict.  Denver has been under the EPA gun due 
to our setting against the Rocky Mountains and our sometimes miserable air .  
It is estimated to  cost  $900+ to put the original, rather worthless, smog 
stuff back on to Moby Dick and it would not clean up the emissions that much.   
1988 technology was just not that good.

Hey Butch,

That was a great truck, and I never regretted buying her from you. In
fact, after I got her up to about 230K miles, I sold her for a
"profit" (not counting several repairs and some minor restoration
work). She never let me down south of the border, and the stateside
breakdowns are now fond memories, like when the fuel pump died as I
was turning across traffic into the path of an oncoming
bus--ironically, on my way to a first aid course. Good times! I sold
her to someone from SLP, so who knows, she and her great big winch may
be roaming the sierra even now.

Like Bill, I have been driving two Tortugas that many of you know.  The first 
was a 59 1/2 ton I bought in 1961 , the second the 3/4 ton with a one-ton front 
axel that Ken Laidlaw bought new. When he got tired of his Big Toy, I bought it 
and put it to Real Work . I ended up after 30 years with over 480K on that one 
(with four hart transplants) .  In 2003 I gave it to my son in Albuquerque. I 
was trying to get it to an NSS convention and put it in the auction,  but it 
did not quite happen.  Pity! 



The 3/4 ton  1988's were about at the peak of Suburban toughness and 
durability, although there wa s a sight degrading compared to my 69, but only 
an expert would see it.  A far cry from the truck-on-a-passenger -car-chassis 
that have been produced since.  I really would not want one of the new ones - 
there are better vehicles out there for my - and most cavers -  purposes. 



The really smart upgrade (along with a bunch of other things) t hat  Dan added 
to  this one is the 25% Gear Vendors overdrive.  I think he is probably quite 
honest when he says he got 16-17 MPG in overdrive driving 75MPH on the 
interstate from Seattle to Estes Park ( 1500 miles).  That truck is about 6000 
pounds, empty.   You should read all the upgrades he has done to the thing -  
on the DropBox link.

Howdy Texas Cavers,
Tonight we are going to have local cavers talk about some local caving.
Yay! Peter Sprouse will be sharing about recent caving in Hays County and
Bryce Smith will be talking about Hendrix Riverside Caves.  See you all
tonight! UT Grotto meeting - Wednesday from 7:45PM- 9:00PM
University of Texas Campus in 2.48 Painter Hall (156 West 24th Street,
Austin TX 78712) http://www.utexas.edu/maps/main/buildings/pai.html

For information on Underground Texas Grotto activities, please see
www.utgrotto.org

Before the meeting, take advantage of Sao Paulo  www.saopaulos.net  for
happy hour specials.  This area is the best place to park and meet folks
walking over to the meeting.  Then after the official meeting, we continue
with the decades long tradition to reconvene for burgers, beer, and tall
tales of caving at Posse East.  www.posse-east.com

Do you have some information about, how you can calculate, tourist capacity
in caves?

Since tourist have to stay on the trail, you first have to calculate the area 
in square meters of the entire trail.   Presume it is just a very long 
rectangle.   Then imagine each tourist is a circle with a diameter of 1 meter.

So how many 1 meter diameter circles can you fit in the imaginary rectangle ?

Then you have to multiply number that by 0.80 because 20 % of the passage will 
have natural and man-made obstacles.

Then you have to consider are there wheel-chaired tourist.  And is the path 
one-way or two-way or three-way.

And you have to figure in how many restrooms you have, how fast the tour moves. 
 And how many emergency exits are there ?   Or if there is a "teleferico" or 
elevator.

And with any math #, you just have to multiply or divide the traditional pi 
number to get a number that sounds logical.

The number always comes out to be around 100, plus or minus one.

I’d have thought the capacity could be calculated by seeing how many you could 
fit in there before they ran out of air and stopped breathing ;-)
