If what we heard last year is still true, we can go ride trails at Maplelag for free as long as we don't bother anyone else who is there (for summer camps, etc.) and don't go into the lodge.
Is anyone else interested in taking a weekend in July and going down to camp nearby and ride the trails? Aside from riding, we can jump in the lake and grill and (if Toaster can come) drink some beers.
This is the place where we will be hosting our MTB races this September, and has a great deal of terrain.
For those who aren't familiar:
