Frank and Others,
I'm having a tough time figuring out if my billboards are going to be visible from a certain setback distance. Is there a trick or a rule that can give me an idea of what would be appropriate? For instance in a wide open area with nothing around the following size billboards should not be further away from the road edge than:
8-sheet -> 80 feet
30-sheet -> 150 feet
bulletin -> 600 feet
I know there’s a lot of factors here, but I could really use some help on this.
