I was driving past the Rinker cement plant in City Point (near Cocoa, FL) Friday and saw a string of Ortner hoppers being backed into the plant. Two of the hoppers had large, maybe 8'x12', billboards hanging on the side of them. One was advertising the Florida Marlins. I didn't get a clear look at the other one, but it may have been an "operation lifesaver" ad.
Took me back to my youth when lots of cars had something (besides graffiti) painted on them Do railcars today have enough visibility to become the next "city bus" type of advertising venue?
