If I had the money, a drill, and the ability, I'd definitely install those. personally, I'd be o.k. with installing a remote controlled machine gun to mow down trespassers, but of course that's not allowed. I just had a knock at the door. I am still in my PJs, so went to grab a robe before checking to see who it was. By the time I got downstairs, I saw a black guy and a scraggly looking white guy going door to door. I know there's no one next door, and the others wouldn't open their door to them. There's supposed to be no soliciting here, but occasionally, we'll get one. They broke my gate even further than it was already broken, by pulling it, rather than pushing. I don't know why people can't understand if it resists, try the other way, but everyone seems incapable of comprehending that. On the plus side, I went out to pull the gate closed again, since they were also incapable of closing it, and noticed I had a package, so at least they weren't package thieves.
