too many!
Bicycling - Road, commuting, and Mountain. Racing/motorsports - autocrossed in SCCA events since 1984, also worked on a pit crew. Model cars, slot cars, model railroading, model rockets, antique hunting, coin collecting, collecting old handheld electronic games, antique firearms, knives & Japanese swords.......metalworking, wood working, making stained / etched glass, fossil hunting, shooting, hunting, fishing, camping, kayaking, hiking, gardening, amatuer photography, stargazing ............. the list goes on and on. I'm sure I missed a few. I guess being a single parent of an 8 year old daughter doesn't count as a "hobby", but i spend a lot of time at that "hobby" as well..........
In my "spare time" I work a full time job or sleep, LOL!
