I'm really into mountain biking, last season I was sponsored and racing semi-pro on the western new york cross country circuit. Unfortunately I didn't train over the winter so I'm not racing this year, just having a good time out riding. If you guys think photography is expensive, try mountain biking: My 4 bikes together are worth almost $20,000 :O And they aren't even top of the line.
I'm also a volunteer firefighter, which takes up a ton of my time, but I love it.
