My neighbor puts away his outdoor decorations every day

If you cold, they cold.

I assumed theft prevention, but if he has a nice lawn, he could also be trying to keep it from dying.

People keep talking about crime, but I tend to hold off on even putting up decorations until a week or less before the holiday because where I live the weather will destroy or launch your decorations, and the storms often come at night with no warning.

So my immediate thought was, he wants to preserve those decorations. It's something I would do if I didn't just accept I'd be replacing a third to a half of my decorations every year because I can't be assed to take them down for storms.

High crime area?

My gas station had a giant dinosaur and a store down the street had a giant chair. They just chained them down like a dog on a leash.

No. I have had Christmas lights stolen, but those were on the fence by the road, we don't have that in this house.

The inflatable things people just deflate and leave out usually here. Everything else just stays so the house stays decorated.
