Could you tell me anything you know about where the RV's are put?

See the Map on the festival website, rv’s  are put in the meadowland Carcamp,

I understand there are no hookups, and generators are only allowed during the daytime.

That’s correct.

How far is the festival from the rv sites?

About 5 min walk to main stage.

Emmylou harris is on sunday night. Can we stay until mon am?

Yes

Can we barbeque at the site? We have an attached propane grill.... 

Propane is OK, no open charcoal though.

Are there enough RV sites?

Usually plenty of site available, it’s a large area.

Thanks
Patty
