Played a lot of euchre on the car ride down to it, then a little bit of a bid euchre variant that's apparently fairly local to our region. At one point in the car ride we only had three people interested in cards, but the only game I know well enough with three players is skat and the car is simply not the place for it and I'm not going to teach the bidding without printouts. So we took a break.
I learned a nice Indian game called twenty-nine - it's in the jass family of games (like belote), but it's a little simplified. I think it strikes a very nice balance. I'll keep it!
