Yeah--good idea! And why aren't there any "wacky" teardrops and tiny trailers? The guy with the fish motif is the only one I've noticed that isn't up to formula.
Here in Minnesota we have an ice (fishing) house parade at Lake Mille Lacs with many, many wacky houses paraded through town on their trailers. I seem to recall such events in Wisconsin and New York also.
Granted, we might have to haul them around with a disguise on them--or on us--but it would be a lot of fun at a get together.
Hmmm... could we even get into campgrounds with trailers that looked like deranged toads or pumpkin coaches or whatever?
