Anything adrenaline pumping. I've been skydiving, white water rafting, bungee jumping, repelling, basically if it scares the shit out of me I like doing it. But I've also got my relaxed side, from just reading a good book or playing fetch with my dog in the backyard. I've also just started dabbling in photography.
