For the past couple years, the owner of FVOR has let our club camp out right on the grounds of the riding park, with the place to ourselves after regular hours. Sweet. Ride Sat afternoon/evening, campfire cookout, and ride Sunday morning. FVOR has easy trails, challenging trails, and a nice small MX track with small tabletop jumps. Basically you can ride according to your ability and your own pace. Any bike from little MX peashooters to big dualsports are fine, but I'd strongly recommend the knobbiest tires you can fit :-)
The deal is- we arrive in the afternoon, pay the $25 entrance fee, and sign the required waivers (they have a manager on grounds to assist). We are responsible for the gate after closing time. Sleep/wake up when you want and get in some riding. IMO, this is quite a nice opportunity for us from Wardy. We are on our honor. Kids are welcome.

Here's a link to the waiver we need to sign to participate in this event: (I'll have a whole stack on hand as well)
