thorn: oh yeah, the neighbor knows very well I am armed (practically everyone up here is) because I have a shooting range in my "backyard" and I killed his dog last summer because it was coming onto our property and killing our cats. I actaully thought the latter was a good thing because if I am that protective of my cats, then imagine how I am about my daughters ...
I am convinced in my own mind that when the little dog alerted and my daughter went back to the house, whoever was out there expected daddy to be coming out with a gun shortly, and that is why they vamoosed.
Yeah, I did put up some no trespassing signs right along his driveway easement, just for "effect".
As far as shooting trespassers, the general rule in Montana (not the law) is that you might very well get shot trespassing on someone's land - might not be a justified shoot but that doesn't matter much to the dead person.
I'm not really excited about spending a bunch of money on fixed lights and cameras, etc. For one thing, there is just too much country to cover: 40 acres total, and about 2-3 acres of "yard" that is "developed" and/or used daily. I think going out and checking the area myself is as good a solution. We have some other neighbors a few miles away who think yard lights are a bad idea, because the dark actually gives them an advantage on the home turf. They have only lived around here about 85 years though
It's cold again - about 0 to 10 above, so I don't expect much lurking in this weather.
If something does happen again, I really want to catch the person(s) and detain them for LE.
