Watch that bridge!!!

That is why when I measured the height of our rig I laid a 2X4 on edge and measured to the ground on both sides. Averaged the two measurements(11'6" and 11'5") and figured 11' 6" would suffice, until I got to Quebec, ON, CA and the clearance was in meters(just meters, no feet and inches). A very friendly(not) French-Canadian highway worker yelled and screamed until I entered the tunnel. He was right, it was higher than my rig. My appologies but I was worried and not thinking straight.
