Step 1: Find a City with a Friendly Sign Code. We know this is easier said than done, but those cities are out there, (as well as "County" properties) which have workable permit processes, or are more "Sign-Friendly".
The trailer involved was much like the ones pictured here. 8' high x 52' in length. Hard to imagine a faster solution to R&R graphics, but if anyone out there knows of one, please let me know. Also, can anyone send in the amount of labor it would take to remove and replace 8' x 52' of pressure-sensitive/decal for comparison?
