We do many of the things on your list: we're both avid readers, we love to snowshoe and XC ski. We're also into geocaching; just picked up 5 the other day while down here in FL on vacation. Although I haven't been active in a while, my Amateur call is AA8TC, and I also am an amateur photographer and a woodworker.
We've been heavy duty boaters for many years, but we're sort of giving that up to get back into camping. The sailboat, 2 dinghys, and motor are going, but we plan to keep two inflatable kayaks. My wife is also addicted to the Food Network, and is an excellent and creative cook. We both love to watch Alton Brown and his show Good Eats, going so far as to TiVo his show so we don't miss any episodes.
At one time we were gardeners, but just don't stick around enough to properly take care of one.
