Photography, definitely. That got me flying, as well.
I'm also a golfer by profession, so THAT quit being a hobby a long time ago... Grr..
I also love tinkering around with technology.. Obviously. In particular, phones and computers and networking and stuff..
I collect music. All formats. I was around in the 90s for the entire Napster fiasco so I have everything Digitally up to that point.. Lol.
I collected football cards as a kid(still have them) ... Wish it was baseball cards, Id be retired. Right?
I used to build models.. I'd like to get into that again... Hmmm..
I also really want to get into ham radios and or amature radio... Is that the same thing? I want both, then.
