Acting- This has always been high on my dream list but I realize I'm past my prime, tall and do not live in LA. and have never taken an acting class. I have been in a few plays and maybe will look into this further. For now it's on the long list.
Amateur Radio- "Ham Radio" strangely this interests me... maybe because I spent hours and hours eating M&M's with my Papa listing to police scanners and talking to long haul truckers from his living room. For now I'll keep it on the list.
Arts- The arts, pretty broad title here. If your hobby is "the arts" that seems like you might have to really bee involved in LOTS of arts and various elements which sounds like a lot awkward moments and laughter might happen.
