it is a interesting and desolate place. I obviously stayed on the roads, and I went for 40 minutes before I saw another human. I would never go out into it on my own on foot.
It did give me a pause as I walked up to a car from 1985 to start and get me home. Of course, my Porsche runs like a Porsche should. And since I do the maintenance on it since I bought it 1995 I felt sure it would get me home in comfort.
Have fun exploring the area. And unless there is a reason to split up, I wuld suggest you stick together. Have fun!
