Four-wheeling, hiking, guns & shooting, sailing when I have time & money.
Used to enjoy masonry-type construction (brickwork, stonework etc..) when I was much younger, thinking about getting back into that and building some things around the new house (outdoor grill/oven, cold cellar etc..) when time permits.
I always loved flying and was always afraid of heights, but was never able to reconcile the two. Took flying lessons for a while until I found the exact point where the love of flying and fear of heights met -- tipped over in a stall with the windshield full of "ground". Spins were OK but I could never stop panicking in a stall, even in a C172 which has the most gentle stall you could imagine.
I always imagined I would enjoy blowing things up but have never had the chance, at least not since we were making nitroglycerin, gunpowder, and various other explosives in the high school darkroom
