  • Be considerate to other trail users and the environment.
  • Be safe. Ride with a buddy, especially if you're unfamiliar with the area.
  • Be self supported. This isn't an organized ride with support. I'm just sharing a route I'll be riding this day, you're welcome to come along but you ride at your own risk.
  • Be capable. You should have some confidence tackling the terrain and distance you're attempting to ride.
  • Enjoy the trails.
