Man, around here the best Mountain Biking is to be had in the summer when all the trails up in the Cascades melt off. We ride all year long, but the truly epic trails don't melt off until July. In the winter we ride the lowland trails, which are fun but they are not quite the same as the big mountain rides.

Added on edit:

Here is my newest bike - it's not this clean anymore. Most everyone around here seems to have carbon fiber road bikes, I have a steel road bike and a carbon fiber mountain bike!
