The presale tickets were $60 for the weekend. They'll be more than that now but for two solid days of music that's not bad. It will be two stages so there's very little down time between sets.

Note that this is a much different experience than a usual free show at Hartwood so yes, they're trying to make their money through other means.

If it's like last years event, you're allowed reentry so there was the option to tailgate at your car and not rely on vendors for food.

If festivals aren't something you're used to, I can answer more questions about what to expect though I'm no expert.
