Anyone out there looking for a job? Come to southern Oregon. It's beautiful
with four distinct seasons and lots of recreational opportunities. The Medford
District is a really friendly place to work. Not many caves in the area, but
there are some active grottos around both in SW Oregon and northern California.

The 6 minute video-clip below just has nature scenes, but it is worth
heating up some popcorn first, before viewing it:

I have not heard any new news about the cave found by the road
construction crew.
One news-site says that it was to be filled in by mid-October.
Anybody out there have new information ?

Wow, what a great TCR, lovely site and weather! Thanks to everyone who made it
happen - Don, Stefan and the cooks, Pete Strickland with the hot tub and sauna,
and everyone else. It was a hoot.
Cheers,
Denise

I second that, but even better was seeing many good friends. It's been about 4
years since I was last able to make it to TCR. I hope it won't be that long
before my next one.
My thanks to all who make it possible.
