Thought I would put my experiences in here for you. I camp and travel alone with my two collies, one of which is an excellent watch dog. I stay in both private and State Park campgrounds and never feel threatened or worry about anything. When it boils down to it, you can have a home invasion in your own home anytime as well. I leave chairs, BBQ grill etc., out ok my picnic table or sometimes put it away in the back of my truck. Never had a problem. Now coolers can be another matter. Both 4 legged and two legged can steal or demolish one. Best to keep out of sight and smell.
As to weather, the best defense is to be weather smart. Check the forecasts for areas you are camping or heading for in the morning and again at night. We are at the mercy of mom nature no matter where we are. I had an experience in SD two years ago, where a violent storm struck in the middle of the night. Nothing in forecast before bed indicating any storms. I thought for sure we were having a tornado as the winds were rocking my trailer. I evacuated with my dog to my truck. Never saw a storm like that with continous non stop lightening, driving rain and wind. . I could feel my Trailer shudder inside the truck. The power went out as well. When it finally ended a lot of us went into the main building for awhile till we made sure no more were coming. The aftermath was the roof torn partly off the campground office, a pop up camper knocked on it's side as well as a new 5er still hitched to the owners truck, stuff blown all over. Wind was clocked at 90 mph. I think the only reason my Trailer stayed put was it was hitched to the truck with the WD bars etc. but all my stabilizer jack blocks were gone from underneath. So it apparently either rocked a bit or got lifted a bit. Also had a metal picnic table thrown against it and punctured a hole in the siding. Nothing duct tape couldn't patch. But nobody got hurt and only two trailers flipped out of all that were there.I might add, the owners were terrific despite suffering damage to their office, it's computers and reservation system information and store. They were out there in a flash soon as the storm let up, making sure everybody was okay and emergency personnel were there just as quick. So you just never know. Your house isn't safe either if mom nature goes on a rampage. So we just go and be aware. Can't stay home for this, that and the other, or we would never go anyplace.
And I might add, anybody gong east or west on I-90 in SD. The Kennebec KOA is great. The owners are the most caring people. I will stay there again and maybe next time, no storm
I was told by some native SD campers there, that storm was way out of norm for that area. They get bad weather, but not like that.
