riggers24,
How about amateur radio (ham radio), computer graphics and photo manipulation? The first I've been a part of for almost 40 years, the second for only about 15 years. Use the second to 'change' pictures to 'suit' any situation, then the first to send those pictures to other people almost anywhere in the world. A sure way of getting in trouble with the people in the pictures, but fun.
Someone mentioned old cars. Been there done that too. Wish I'd finished the last one before I retired! Anyone want an old Ford pickup (almost as old as me)? Best way in the world of throwing away money. Also lots of fun, and I made a killing on the one before this one!
Also used to love playing pool. Wasn't half bad till my vision sort of got crossed. Now, there's just too many balls to mess with.
Most fun I have is watching people. No idea if that's a hobby or not. Also no idea of how to give an example that wouldn't get me barred from the forums! lol Amazing what you see sometimes. Never figured out why some of the 'fads' going around don't go straight into the ground, but, some of them are very nice (I'm going to take up 'body-painting' as soon as I master this @#$ airbrush! If my doctor will approve it.).
Flying was also one of my hobbies till the cost of fuel got so ridiculous. The real ones, not the little ones. And why anyone want's jump out of one I'll never understand! (Almost tried that too, but chickened out.)
Had lots of 'free' time while working so have sort of mixed all of the above with work, at times. Visitors to the station often were shocked/discouraged from comming back, and a few came back anyway (really odd ones!).
My most favorite hobby is complaining. My bosses finally understood that if I wasn't complaining I wasn't happy for some reason. Almost took the fun out of it...
Several other 'hobbies' but like I said, I don't wanna get thrown off the forum...
