They passed a law here in Kansas, that if you get hit by rocks it's your fault for following to close. Allot of the truck have signs on the reading, "Stay back 500 feet" ya right tell me who does that in most kinds of traffic??? and yes it is the law they have to be tarped, but the problem is now the rocks on the little 6" to 8" lip the below the dump gate that now is a great place to hold rock and dump them while going down the Hiway... Nice.. Thanks Guys Thanks..
