You are welcome to come and camp on the property Friday through Sunday or any days therein!
Depends! If you are coming just for the day- bring yourself and your dancing shoes. If you are camping at the venue, bring your camping gear- including food for the meals you plan to eat there that are not the wedding dinner- we got you there. Everyone should bring a swimsuit, just in case :)
It will be early August in Vermont, which means it can get pretty hot. Wear any outfit that feels good to you and will keep you cool.
