Cool bike. I have a Specialized Hardrock that I dig.

A couple of tips: try standing on the pedals when you're going over rough terrain. You don't have a rear suspension, but your legs can compensate for bumps and prevent your junk from slamming into the seat in an.. *ahem* uncomfortable fashion.

When you lay your bike down, put the chain on the top side. Your chain is less likely to get dirty that way. If you haven't already bought some kind of lube for it, I recommend a product called Teflon-Plus "Dry" by a company called Finish Line. I got a 4 oz bottle for $6 at a local cycle shop. The reason its "dry" and not "wet" teflon is because, supposedly, its less likely to come off if the bike gets wet. YMMV, but it works great for me.
