Slow down a minute, if you get caught performing such an act you will go to jail and cause seriously bad press for all of us reptile lovers. Why dont you put up some signs warning drivers to keep an eye out - contrary to popular belief turtles can be hard to see for some folks - and drive slowly. Diamondbacks are protected in NJ arent they? Why dont you mention something to the local Fish and Game, at least they might lend an ear to your problem. Just my thoughts, I'd hate to see ya get in serious trouble or anyone get seriously hurt, a flat at even 30 miles an hour could have dire consequences. I know Ive had them. Besides they could crash their stupid SUV into the wetland/marsh where the turtle originally came from, it would come to rest in a steaming (possibly flaming)crumpled, oil, coolant, and gasoline leaking pile of rubbish. They would have to call a HAZMAT team in to clean it all up, the traffic would be backed up for miles and everyone would get home to tired and pissed off to read Michael Moores new book "Stupid White Men". Consequently they wouldnt learn that a complete weasel was running our country, and lining his and his buddies pockets with wealth stolen from YOU and ME and the rest of This Great Country We Live in. Your time would be better spent going to see Farenheit 911.
Best of luck
