If I can't find a place to open it up to as far as it will go, I may get a friend with a cell phone at the other end of where the stretch of road is and go for it. There has been a lot of state police around here lately, if I got caught at that speed I probably wouldn't have a license for a long time. Oh and I'll try to take a picture of the speedometer too, if I get ***** enough to hold the steering wheel with one hand .
