The RV park in Rexburg where I stayed for 10 days while sick is rather unique as campgrounds go. All purchases are done on the honor system. I saw the owner only from a distance and never spoke with anyone associated with the park. Rental fees are put in an envelope and deposited in a slot in a small building. This Red Box is in the laundry room as there are no coin slots on the washers and dryers. There was a table of handmade/white elephant items that were bought by, again, placing the money in an envelope and putting it in the Red Box. I like the concept, and assume it works for them.
