I am the furthest thing in the world from a mom taking her kids camping solo (married man with no kids), but I will say that in my entire lifetime of camping (30+ years since I started as a young boy) I've only ever been nervous once, and it was miles into the wilderness (backpacking trip). You'll likely find that most folks in campgrounds are terribly friendly, and their biggest faux pas might be trying to help a woman going it alone a little too much (with the noblest of intentions). This is strictly a personal preference. Ever since I've been old enough, I always travel (wherever it is legal) with a personal protection weapon. I will, without hesitance, say that never once have I ever felt the need to even reach for it, but I do sleep a little better at night knowing it is there while camping. A previous post said "be smart, but don't be afraid", which I think is phenomenal advice. Get out there and camp! Enjoy yourself!
