Judy - I did an overnight in a park in MS that was down close to the coast and actually in a small town, but still in the pine trees. Now I had done a tour of the campground because they let me choose my sight and I knew where the other campers were. But I discovered water coming out my trailer when I hooked up the water supply - I wasn't able to do a thorough job of trouble shooting so had to turn the water supply off. That meant using the facilities in the middle of the night - which had not been in the original plan when choosing my site.
For some reason, that night I was a little uncomfortable staying by myself and having to walk to the restroom anytime I had to go. And I finally decided that it had to be the trees and the unfamiliar campground.
And that really was the only time so far I have been uncomfortable - nothing I could really put my finger on. Maybe there were spirits in that campground - it was that kind of atmosphere.
Oh and the water leak turned out to be totally loose connection going into the fresh water tank... tightened it when I got home and was good to go.
