No, this isn't an April Fools joke - KGB has been reopened.  The trail starts at the pump track and is clear the entire way.  We are still working away at upgrading and rebuilding sections of the trail, but it's fully rideable.  Just keep an eye out for new work this spring.  I'm guessing we'll be done working on the trail by mid May.  KGB is an advanced trail and is recommended for riders who like a little more than just xc trails.
