Gosh Charlie. It seems so clear to me. A trailer has been shown by Bill to be a proven method. Jeff & Eva brought you here in the first place, have that perfect sized trailer, and the 4 wheel drive Jeep to pull it. They are coming to the event and have expressed an interest in going to the museum, with possible ice cream side trips. I have some ground cloth plastic they have borrowed before. I think you just have to talk them into letting you toss their bed onto the plastic while you use the trailer. Sherpas are really expensive this time of year here.
