I was out by Cedar Pipeline Ranch and this Toyota minivan goes zooming down the road, which eventually leads to a gate that is an entrance to the TTR. It looked very much unlike what a base worker drives, which is often a white truck. My gut feeling was this guy had no clue what road he was on. I watched via binocs and sure enough, the guy was turned back at the gate. He drove past us looking a bit POd.

The Cedar Ranch Road appears on many map databases, but it is not always marked that you can't cross it.
