Dharmabum, I'm not sure about this. Maybe you'd be better off going to the Old Songs website and e-mailing them using the address there. I believe there is no one at the gate, and I believe they have one of those blocking arm thingies.

I don't know what sort of a set-up you'll have, but if it's mobile enough, you could always stay in the parking lot the first night. You can walk in and out of the gate, just not drive.
