Please don't ride on trails after rains when wet, preserve trails and make sure they are dry before riding. Major wash area - be on the lookout during monsoon season as some areas may be impassable.
Fast and fun. However, watch out for the sudden dips into washes that can be a bit of a surprise given the loose sand at the bottom. Some areas are sandy, so until you're familiar with the area, be sure to be careful so that you are still in control. (Not so sandy that the trails are not worth doing, just in certain spots)
