One more suggestion, if there are hardwoods between the thicket and the interstate and the wind is right you may want to set up on the interstate side also, I think you will be pleasantly surprised, I have popped more than one in areas like that, because most hunters think it is to noisy for deer to be there, think about the number of deer you see road hit along an interstate.
