WANTED: Outdoor space for event(farmland/free land/even a backyard)

Large group in need of a decent sized parcel of land for a birthday tailgate on the night of JULY 21st(Friday). Last second change of plans means we cannot use the property we previously planned on. We need a decent sized outdoor area to host a large gathering(60+) for 2-3 hours before going to the bar we have rented. Busses will convoy guests to and from property, meaning there will be no cars/drunk drivers/no liability. We will provide large tent covering as well as port-a-johns for obvious sanitary reasons. A crew will return the next morning to clean the property and clear the setup. Payment is negotiable, cash. Nothing is required from landowner, easy way to earn some extra cash.

Didn't know where else to post this, send me a pm if you can help!
