I don't know how related some of these are. Outside of things like hunting, reloading and gunsmithing.
Ham radio, W4ADS, extra class. (I passed Extra, just to get into the vanity call sign pool early. Not very noble reason I suppose.) Not active much even on VHF. Have 25' tower, but no HF antenna. Really want a StepIR, but can't afford it.
Electronics in general. Building kits and circuits. Yes, I use to own Heathkits.
Programming computers. Old school stuff. Assembler, machine code, drivers and things like COBOL, FORTRAN, SQL and CICS. Heck I even knew RPG and PASCAL at one time. Does SNA ring a bell with anyone? I still enjoy collecting the odd data base and performing analysis on it, just for fun. Want to know how many different first names there are among US ham radio licenses?
Theater/theatre, performing arts, is in my family blood line. I'm more of a stage manager type, but also do lighting. I'll probably do volunteer work for local high schools when I retire.
Sailing and just spending time on the water in general. Scuba diving which I haven't done in 40+ years. Loyd Bridges and I could have been best buddies. (My scuba instructor was murdered shortly after I completed my certification. His wife cold conked him with a pipe wrench then cut him up in pieces and stuff him in a 55 gal drum. Nobody particularly faulted her for it.)
Fishing. Nothing fancy. Put bait on hook, toss in water, drink beer.
Airplanes. Was in the USAF. Went through ground school, but never got the flight time. Worked on C-124s, C-141s and C5s. Sadly, all my bases and missions were classified to some degree, so the only picture of me is with a B-52, which oddly wasn't classified.
