I've already pleaded to move this off of boatball day for my aquatic friends

It seems like there are many new riders around, so we are holding a little informal skills clinic this Tuesday, 5:30 on the Wolf River Trails between I-40 and Summer Ave. There is a wide variety of logs, log piles and log rides here to practice on. We will try to cover as much as we can, from braking properly, to cornering faster, riding over logs, log piles, off ledges and how to crash spectacularly. If we are lucky we can watch John fix a chain yet again 
There is parking in the Garden Ridge lot next to the entrance to the Summer Drive-In or you can ride the trails from the Germantown or Walnut Grove trailheads. We will be riding in, so don’t look for us parked at Garden Ridge
