Re: Anti Theft Idea
For my weather cover I just use some of that cheap plastic tarp that you can buy at a big box store. 7 x 9 ft works better than the very small ones. Those are 5 x 7, I think.
I use small spring loaded clamps to hold it on.
If it ever does get vandalized it's not going to matter much since it can be replaced cheaply. I've forgotten the cost, but it's surely less than 10 bucks.
