Threads often take on a life of their own, especially around the campfire. ;-)<br><br>I hope you haven't taken my comments as being critical of you or anyone elses opinion or experience. It was never meant to that ta all.<br><br>I do see the gist of your point. My folks live in a rural area of Wisconsin. The neighbors kids were allowed to drive anything on the farm, whether it was a gocart, tractor, truck or bulldozer, when and only when they could reach the pedals. Believe me, this was at a much younger age than our teenagers applying for drivers permits.<br><br>The environment my kids grow up in would not tollerate or support such application of measurement. The farm has much fewer fenders and mailboxes to dent or knock down. It is restrictive, and I lament that to some degree. But there are practical reasons for many of these unwritten guidelines. But then, all but my youngest, who can'treach the pedals, drive Grandpa's tractor when we visit them.<br><br>
