thomas_g_feed) just participated in a BANG ("Bay Area Night Game"). Another friend, 
lessachu, has been involved for quite some time in these games. They really sound like a lot of fun, though it also sounds like there's a lot of awfully clever people who have been playing them for a long time, so it's a bit daunting. The next one's in Petaluma, which is about a 90 minute drive from home. I haven't yet figured out what's involved in getting involved either. Hm. *ponders*
