I would agree to all of this. There aren't bars on the windows of the neighborhoods near this campground. There isn't graffiti nearby (but in some areas there is, just like almost any city).
I don't think motion lights or maybe remote control lights that I can click on if need be from inside the trailer are all that diminishing for my application at this particular campground.
I already have a dog. A black Lab. If he goes with me he stays inside at night and is not much of deterrent. Haven't ever seen someone with a guard dog outside their trailer all night, so I think that suggestion is kind of unworkable.
