thanks blue....but that velcro tape leaves a residue...ever try to peel it off the window?

as for inside the bumper....really? Is that a viable option? Is there a way to make it completely hidden?

i find them unsightly and then there is the tape issue...even suction cups leave a mark, though not permanent.

Maybe just holding it up is the easiest thing...I guess I don't cross THAT MANY tolls....
