I put a lot of effort into my signage along the highway and it pays. Everything is professionally done and well built as in extra heavy vinyl with triple stitching and aluminum backed signs on a sturdy frame. Otherwise the weather destroys them. It takes awhile to build up a supply of different signs but then you can rotate them so things look fresh. The signs bring in more people than any other thing I have tried. Just make sure they are BIG and simple so that the message can be absorbed at 50 mph.
