NJ road

I'm in NJ this week for business. The road of NJ is complicated. There are U-turn or left turn designated roads. If you want to make a left turn, you need make a right turn first and turn around the designated roads. It is difficult to explain.
Gas station is also special. There are no self service gas station in NJ (I think). You have to wait for staff for filling gas. I prefer the self service gas station.
