Not really a 'hobby' but I'd have to say Freemasonry (also York Rite/Knight Templar).. I currently serve as the Lodge Secretary (Northern 278, New Hope Alabama).. My friends just don't get it but unless you're a member you wont...
It's disturbing to see so many instances where reading is considered to be a 'strange hobby'..

That's an interesting line of work. Also, it seems like one of those ninja-jobs. You're there doing your thing, but nobody knows it. You affect the consumer, but nobody realizes just how much. What made you lock down on that as a discipline?
Drumming. I've been a drummer for the better part of 35 years. When my friends see just how many sets I have (4) they kind of roll their eyes.
Now that you mention it, I own two 60s vintage Ludwig drum kits, and have been drumming since 1975. I've toyed with the thought of selling one of the sets, but can't bring myself to do it.
