What all do you want to do around here? Depending on what kinda lifestyle you have.. there's something for everything. Sacramento and San Fran are each less than an hours drive as well as Oakland and San Jose if you you want more big city options. whatever you can think of... San Fran has it.
Infineon Raceway is bout a 40 minute drive and there are always trackdays going on around there.
It's been raining the last couple days but weather is typically mild and nice during these times.
When I did ALS back in late 2002, it was quite easy. At least one weekend will be devoted to some sort of volunteer/voluntold community effort thing or group projects/study time. they encourage teamwork and wasting alot of weekend time doing stupid stuff... least thats how it was back when I went.
As far as bikes go... try going to
www.bayarearidersforum.com there's tons of stuff there from group rides to social meetings to everything else under the sun.
I've been stationed here at Travis since '98 and love it.... definately a good time.
