I'm strickly a XC rider, so I usually head out in the boonies. I make sure I have a first aid kit along with my blowfish, camera, bug repellant, lighter, compact jacket, pump, spare tube, and an excellent map of the area. I also take my cell phone, for what I dont know, because so far, there has been no service in the areas I ride in. I usally have a ziplock baggie with some fig newtons, you know, "it's not a cookie mommy, its a fig newton."I also carry a business card for id purposes in my pack, just in case I run off a cliff, they'll know where to tow the bike.
