No recreational boaters, though a few ski
No gardeners
No recreational flyers, wing or rotor

Most of the responses were not hobbies but sports, which is
ok, but I was more interested in hobbies, which in my mind is doing something creative. Getting in shape and having a
a good time with it is a positive pursuit but not a hobby.

Bufus: Actually it is good that you find bewonderment in the
dark skies. It is more gratifying than audio many times. What makes amateur astronomy so cool is you just need your eyes, you look up and see the whole milky way. It definitely
makes you feel a sense of wonder. Oh you can go hog wild and spend a fortune on telescopes, but you need not. Plus it can very creative in an artsy kind of way with astrophotography ( probably the hardest photography to do) and it can be very precise with a definite scientific bent.
I mean real science that is useful to the professional community. I personally straddle between audio and amateur astronomy. I take long draughts of both.
