I haven't taken a poll but I would bet that most of us have, and have had many other hobbies. When I was a kid I loved reading about WW1 and WW2 because my Dad and Grandpa served in these wars. Airplanes, jets, rockets/Mercury, Apollo etc.. Model building, kite building, model rocket building, and I could many more that just burned out. But the one I stuck with was Airguns. This started in the 70's... As I said i'm sure others have had this many and many more but I'd like to hear about them as hobbies have always been a way to calm my ADHD. Go!
