Anything thorny
Would cactii work as far as lining the perimeter entry points or do they grow too slow? Are there any that grow really fast?
I would think that any thing that has a lot of sharp points would work.
One of the ladies that lives in town has a shrub that has red leaves in the spring, and then they turn green for the rest of the summer & much of the fall. I don't know what it is called, but it is very atractive and has some killer thorns.
The old gentleman at the end of my road planted Black Locost all around his fence line. I woundn't crawl through that fence for anything.
I live in the country, and I am a looooooong way from being a youngster.
Some of the folks that live out here are good to watch out for each other & some of them are just watching to see what you have and when you my not be home. It's important to know who is which.
I do have a couple of guns (which I've never had to use, except for snakes), and I have carefully built a reputation for being "a little odd". With that, along with the pricky plants and the dogs, I feel about as safe as I would anyplace.
Certainly safer than some of my friends that live in the city.
