most places i have parked at. the bg fears you more than you fear them. as most drivers, rvers carry a bang stick or six.. a dog of three that will bite.
but if you stop and the area gives you the jitters keep on down the rd.
i have over nited in many a parking lot. side/ back street. even in a suburb.
only time i got the jitters was out in the open desert. along hwy 395 in ca. a pu stopped next to me. i just started up and drove away. wanted to be alone in that area. and it felt strange someone would stop right next to me that way.
so i say go with your gut.
