I've been playing the SOM games since the mid 70's. Like you I only do cards and dice. I tried the computer versions of a couple of the games, but just didn't like them as much as holding the cards and rolling the dice. Of course when it was discovered that some of the results of the computer football game were being secretly re-rolled to produce better statistics, that drove me away from their computer games for life.
I don't know if people here trade SOM cards, but if you're looking for an excellent Strat community, try www.stratfanforum.com. It's a very active community, although I don't go there as much anymore because a good percentage of the talk these days revolves around the aforementioned computer games. Us cards and dice guys are dinosaurs.
