I figured that's how you found the chair. "Take for Free, all you need do is FIX all the broken parts", LOL.
I have my many years-old folding deck chair, but recently also bought a nice new one at Walmart, for $35 ... oof. I can leave the old one with other little junk as a campsite marker when off for the day. No one would want to steal it.
True story. When I was up in the Sierra last month, I signed up for a campsite in a CG, and left some stuff on the picnic table. I took my old chair with me to sit under a tree at a nearby lake (did not have the new chair then). When I got back a guy had taken over my campsite, thinking the previous tenant had left. The host was gone for the day.
He had moved in his Casita, unhooked it, set up the awning, and basically brought everything he owned out onto the picnic table, so I couldn't really make him move at that point. He turned out to be a nice guy and offered me a beer. He was reading the Epic of Gilgamesh, so we had a good time talking about legends and religion. He'll probably be at RTR.
