Diane, as I usually camp on my own with my child, I have appreciated the momentary friendship of people in the campground. I felt like I had folks who had my back, and we watched out for each other. I also always tell myself that there are far more good people in the world, but the bad ones get all of the news coverage. I haven't had any trouble with break ins or theft. I have had a little trouble with some terrible driving and near misses, but that is a totally different situation. I am careful about securing things at the campground (I grew up in a college town, and know if it isn't bolted down it will walk off...heck, even if it is bolted down it might walk off). I also don't take anything that can't be replaced. It is different I am sure for full timers though than us weekend (or weeks) warriors.
Evan, I am glad the vacation wasn't spoiled by an arrest, but I am so glad people were looking out for you guys. Just think if it hadn't been been you and it was a thief! They would have been nabbed for sure!
Enjoy the rest of your trip!
