Another bump from the dead!
Reno SCCA has $25 per day autocross events at Stead Airport starting back up in April! Plenty of Suby love there. http://www.renoscca.org/
Lots of laid back people making for a great learning environment. It's as relaxed or as competitive as you want it to be!
Also try www.seccs.org
There are lots of Reno/Tahoe members there as well. But it seems that the interest in meets has fallen off lately.
That said, I would love to have some local interest in meets and perhaps weekly drives. We have so many Suby's in the area it is a bit of a shame that we don't have much of a local scene! Let's get one going!
