Aside from hearing couples argue or yell at their kids it's mostly dog stories that I remember. Not sure why people let their dogs run off leash. That's great if your dog is friendly enough to run off leash, but if he runs onto my site especially when my kids are outside without an adult, my friendly dogs will not play nice with him. They do not accept strangers willingly without my invitation (unless you're a very smart meter-reader and travel with dog treats in hand;)). Please keep your dogs leashed.
When we were visiting Mammoth Cave in Kentucky I did have one person screaming when she saw my dog. I have a well behaved, leashed rottweiler that I was walking down the road. He was next to my 3 year old daughter. This woman's little yapper dogs were off leash and ran off of her site and she was terrified that my dog would eat her dogs. I've never heard anyone scream like that from the sight of my dog that's calmly walking down the road. Well lady, you did let your small dogs come barking and aggressively charge my dog.......who happened to be next to my daughter that he protects at all costs. No way would he have let those little yappers come near her. As it turned out, my rottie was calm, cool and collected and didn't pay those annoying dogs any notice which made the yappy dog owner look like a fool. In fact her husband came out an apologized for her behavior (while he pet my rottie). Hopefully she will keep her dogs on her own site from now on.
Several years ago we were tent camping and I woke up to 2 labs trying to get into my tent. They shoved their heads right into the tent flaps acting like the lived there. They were running around off leash all morning bothering everyone. Nice dogs, but I couldn't believe someone had the gall to let them run around like that.
Not an altercation but a funny story. Last summer I left our site to go walk the dog. About 5 sites down, he left a load. I did the right thing and scooped it in a baggy. No trash cans were nearby and I knew I wanted to walk further, so I walked back to my site and without stopping, I gently tossed the poop bag near my camper. Then I turned around and continued on in the direction I had originally been going.
From an onlooker's perspective, I had just tossed a bag of poo onto someone else's site! It was a super busy campground and I did overhear several people commenting, "Wow, did you just see that? Someone tossed a poop bag onto another person's site." Let them think what they want, I gave them a story to tell over the fire that night. ;)
