The FAST boys have really gotten this site whipped back into shape again but it's taken a lot more work than shown in the picture link. This site at one time hosted an IMPBA Internat's race but over the year had fallen into a state of disrepair becoming a dumping site for trash.
It needs more use than 2 record trials a year. Maybe hosting a D-2 race? It's a great site to run at as generally the water is protected from winds coming in from the west.
If you're in the area, stop by. I've driven over there several times just to hang out, watch the action, shoot the breeze and learn something from the guys.
Doug, for you probably the fastest way is to take I-69 arcoss and get off at the Bishop Airport exit. Take that to Saginaw Road, make a left then to Belvidere just before the overpass. The streets kind of zig-zag to get to the site.
