I do a lot with card games. I run a small monthly Spades club and keep the statistics for a small Pinochle club. I also play low stakes dealer's choice poker about twice a month.
Other activities include bike riding, listening to baseball/hockey games outside next to the fire pit, having GoT gatherings, hiking (though this is sporadic due to being concentrated on trips), tailgating/college football, monthly dinner club, puzzling, lake house, farmhouse, gardening, swimming/lounging at the pool, any number of lawn/beach games, fantasy baseball, yearly minor league baseball report (on my team), bar trivia/trivia night, bonfires, barbeques, float trips, baking, golf, tennis, midget/sprint car races (dirt), fiction and historical literature, the occasional read on lifestyle and personal finance, darts, and billiards.
