I enjoy all manner of gridiron football--CFL (can't find any games broadcast 'round here this season), college, and NFL. Arena football leaves me cold.
Other things I try to find broadcast:
I play disc golf, though nowhere near as often as in years past. I got certified to coach Ultimate (frisbee), though I don't generally play. I (silly stick) golf badly every once in awhile. Miniature golf is always a treat. Years ago, I played basketball religiously.
