What to do.........

I go down a road in my neighborhood because of a detour and this road is literally like being in another part of the country. There is one house that has a real caboose train car in the yard and a bunch of vehicles. When I was driving by yesterday I took a good look and saw a Ramcharger pickup that looked to be in nice shape, a 70 Duster that is in black primer and had at least one rallye wheel on it and also what looks like a Road Runner under a cover missing its front clip in the driveway. I am thinking about going to the house and knocking on the door but I do not want to get shot.......hahaha.....Would you knock? or let it go?
