As an old trucker, I can tell you cheap GPS units will bring those guys up the wrong roads... Think how they feel once they are screwed and already started up the mountain... you can't just turn around, you are committed once you start up. I took a 28' motorhome, with my inboard ski boat attached up one of these roads because my GPS said it was ok... Ok for sports cars and bikes maybe... I agree more signage and ban is needed, as long as the signage comes before the fine... I can't understand why any of the locals want to even pull their boats up that mountain either... I have never seen a lake at the top yet...lol. New trucking industry GPS units are on the market now, and they are getting better, but signage, and big bold signage is needed to warn truckers before they even get on 129 and the other roads that are similar...the signage I have seen wouldn't be seen at night, and it just states last chance to turn around, but really doesn't say what they are in for... The road I was stuck on was out of Frankfort KY...I will always remember that experience, as I know any truck that was dumb enough to take the Dragon will remember for their lifetime as well...All for the ban though...southern Indiana has some roads that are now off limits for tractor/trailers now...I found that out the hard way too...but I didn't take the road, but turning around wasn't all that easy...so, turn around points have to be established as well....everyone screws up...but you need a way out...petition signed...
