It's not. I simply interpreted your comment as being RV factories. We've seen a lot of tiny factories, building such things as dory boats, and enjoyed them.
Plus, I never said you could see everything that interests you, just that you could see more of those if you skipped the ones that didn't hold as much interest. Sometimes, though, you don't know what will turn out to be interesting--like the Hobo Museum in Britt, Iowa, where I learned the difference in terms like hobo, tramp, bum, etc.
