We do a vintage camper rally in Vermont, the campground owner invites the public in on Saturday to view the trailers. We also do a teardrop rally in the Adirondaks of NY, not restricted to teardrops, at a state park. Some campers per-register, some just show up, and others not in the group, just camping there, stop by to visit and look. We learned that by owning a teardrop you need to have the attitude that people want to look, and to make them welcome. One time we had to chuck burnt burgers out into the woods and start over because of visitors, LOL, no problem.
