Lots of hobbies. They vary with the season and level of interest at the time.
Started buying, repairing and trading motorcycles about 5 years ago. Began with a really far gone 550 Suzuki and after many trades and repairs i have worked my way up to an 84 Yamaha Venture VXZ1200.
Collecting, trading and selling vintage stereo equipment.
Road bike riding (presently riding a Giant Defy III)
Geocaching (Recent interest but 119 finds and 7 hides so far)
Many others but those come to mind right now.
