Watch that bridge!!!

I know it may seem stupid but as full timers, often in uncharted territory, there is peice of tape above the drivers seat that says 12'9". Whenever I see a low bridge sign I look up and know within seconds if I'm good or not. We love the back roads and thats were the problems are.
