Please don't.   The trails are not built for power toys.  Grant money and volunteers work on these trails for non-motorized use.    Dirt bikes get on the trails at Kincaid (whether from the Jodhpur Motocross Track or from trailheads) and tear the trails up, not to mention coming up on bikers and hikers using the trails.

If you want more dirt bike trails, roll up your sleeves, solicit some grant money, gather some like minded friends and grab some shovels and rakes.
