I love Rounders! I only get to play once or twice a year, though. The only place I've ever seen it played here in the states is in conjunction with various Renaissance Faires or with groups that sprung out of them. I've even known of some of the 'faire-related rounders teams to be invited to baseball games and play in the field a bit (in full Renaissance peasant garb) before a baseball game as a sort of pre-game entertainment. But on the whole, I would doubt that one person in 5000 here knows anything about rounders.
