Ever heard of the saying "a man's home is his castle?" All you gun-toting CB loons live in fear of criminals so you think you "need" to live in a "castle" for protection lol.
Just rent an apartment next to a Greyhound bus station (or better yet live long-term in a motel that advertises weekly rates).
If you don't do this, you will never move beyond your Neanderthal-like thinking.
