So I went Snowboarding this week. It's one of my favorite things to do. When I am stuck in the heat of summer, I am thinking about snowboarding. When It gets to fall and the trees are dying and the cold breezes start to arrive, I am dying to get on the mountain. Finally, it's season and I find myself giddy to drive up to the snowline and strap in. Why do I love snowboarding so much? I always come off the mountain in more pain then before. I always spend way to much money. I am often either way to cold or way to hot. So what is it that drives me to do this crazy sport?
