Had some decent wood Adirondack chairs in the front yard for a couple of years - one day after Halloween they were stolen. These are heavy wooden chairs that would have required a vehicle to move. Who steals chairs?
I HAD a nice bench in front and I have a iron fence locked in the front and some YAHOO also stole it. They would have 2 climb over the fence and then back and the bench was cheap but I liked it in the summer.
People stole our metal garden fencing (the tiny kind that you just stick into the ground.) Sad. I'm sorry this happened to you. We even had to drill our front planters into the concrete to keep them from being stolen. Don't give up. Just chain them down.
