Thanks, Hippie! We're staying in Mary E Illium. Can you go to the other campgrounds or do you have to stay at your own? I really am new, what and where is Run a Muck? Crunchy Frog?
Crunchy frog is the official bad decision of Camp Run a Muck.
In Town Park, there are several historic camps. Large groups of people who have been coming to the festival for years. They end up in the same spot year after year and generally have the same people in them. Run a Muck is one of these.
You can visit Town Park in the days leading up to the festival. Once the music starts on Thursday, you will only be able to access Town Park with a Town Park or Warner Field wristband.
Nightgrass is a series of late night concerts held at different venues in town. You have to have tickets in order to go to those. Check out the nightgrass lineup on the Planet's website. I'd link you to it, but I'm on a phone.
I stayed in Illium my first two years. There was plenty of picking happening there, so you should have several options for where to play.
