Mountain Biking

[Pedigre]

1) Stay hydrated
2) Bring enough water or other sports type drink
3) Never ride solo, though that is really a subjective statement (see #4) - if you are going to ride solo, let someone know where you are going and when you should be back
4) Always ride within your abilities
5) Be sure to pack the tools that will keep you from having to hike your way home
