This Month's Meeting:
Annual National EAA Meeting
Saturday, February 23, 2013
10 am to 12 noon.
Meeting Location: HP HQ Campus, Building 20, Auditorium, 3000 Hanover St,
Palo Alto, CA
Visitors welcome, open to the public.
?
Our Chapter
Meeting
for February is superseded by our annual National
Electric Vehicle Association Meeting. The meeting will be held in the
Oak Room
Auditorium at HP in Cupertino (next to lobby of Building 48). We
encourage all members to travel the extra distance to this important
meeting.
This meeting focuses is like our State of the Union - reviewing the
accomplishments of 2012, looking forward to the goals for 2013 and
introduction of Electric
Auto Association's National Board members (hope you sent in your votes
by mail).
?
There will be many production EVs and Hybrid vehicles in the parking lot, for
people to see up close what is now available from the automakers. More EVs are
on the horizon.
?
It's also a wonderful time to meet up with members from other Chapters around
the SF Bay Area and those who are visiting from outside the area. Should have
a lot of EVs in the parking lot and opportunities to share experiences over
lunch afterwards.
?
Those interested in carpooling over should meet at our regular meeting location
(Rhythmix
Cultural Works, 2513 Blanding Ave, Alameda) no later than 8:30 am or email
ebeaa-at-eaaev.org to coordinate
transportation.

Being an idiot does not make you a 'troll'. To me, the word 'troll' has
some negativity attached. To be a moron is purely innocent
kermudgeninuity.
So... about that windmill on top of the car...

this weekend, and I accidentally Exxoned the driveway."

It might be even more effective if it were given a more general meaning -
"to deliberately sabotage something as a reinforcement of one's own
prejudices." That could result in more widespread usage and adoption.
Wouldn't it be gratifying to see Car and Driver write something like "When
Consumer Reports tested a BMW last month, they brodered it"?
