1- Gun tinkering, reloading, shooting. And, as would be suggested by my presence on this forum, (and my website
www.handiholic.com) Handis are my favorite, though I do not claim to be exclusive and
only interested in them. Pretty much anything that launches a missle has captured my interest at some point. I might include hanging out and surfing the net for shooting related sites (like GBO) under this category, though this activity is threatening to become a category in it's own right.
2- Small but long term continued interest in photography.
3- Also history is a big interest, and has been since I was a kid. My wife and I are recording (audio and video) interviews with veterans, of all services from WW2 to present day with the intention of turning them into a book. We will be including all nationalities, American, Canadian, Australian, British, and if we can connect with some, even vets from the other sides. (If you know any, or are one, open to being interviewed, let me know.)
4- I got interested in airplanes very young, and was an aviation hobbiest for years. Then I started working as a pilot, and it became a job. I liked doing it for the most part, but some of the spark went away during those years. Now that I am semi-retired, the spark is flickering again.
