Here's something new and different!  Leake's Mill in Goochland is an XC style, mostly rake-and-ride style trail west of Richmond.  It has a cool natural half-pipe, some rooty sections, some fast sections, some short but steep off-camber hills, etc.  It's fun!  Restrooms on site.
Meet our guy Steven at 10:00 AM for a guided tour.  Look for the red Tesla in the parking lot.  Check out Trail Forks for trailhead location.
