making things out of wood ("woodbutcher")
computers and information management.
I used to make pottery and hope to do it again one of these days, with my kids. I need to build a kiln.
Motorcycling, but I don't do that so much now that I have kids. I have a 15 year old Ducati 900SS.
In past lives, also rockclimbing, sailing, hang gliding, and lots of other outdoor things growing up.
There is just never enough time for all the fun things.
Fishing is sort of a new passion of mine, as I was never more than an occasional amateur before, but the bug bit me last year. (much to my wife's chagrin)
