I have a locked gate with a big yellow no trespassing sign, the legal kind, next to the alarm sign. The power folks won't cross that gate to check the meter, we went a year before they sent a letter saying they couldn't estimate it anymore. Fedex and UPS honor it, as does USPS, solicitors, and church people.
That said, if you cross that line, you probably know you aren't supposed to be here. Since that is the only point of entry to the property, there are no excuses you didn't see it.
Also I live off the beaten path, in the back of a bunch of woods, a small house on over an acre of 100ft. plus trees. Some old growth hemlock and such, we get no sun. Anyway, I have no illusions as to how appealing our home would be to an intruder.
So when I get a knock, I don't answer it, I don't even look. I just yell "Go away!" If I hear funny noises or they don't go away, I'll grab the M4 and go clear the property. If they are in need of help, I'll render aid, but cautiously. If they ignored my sign but are innocent, I'll lower the weapon and just yell at them and make them leave. After living here for a year and a half, I haven't had one knock on the door that I didn't expect. So logically, the ones that do knock should be treated as intruders.
And my friends? I have an army buddy that I trust like a brother. He has his own key to the house. I either trust you or I don't... No in between. Know that invasions also happen often to folks that have been cased already, ie, friends or acquaintances were involved. Seldom does someone committ to that kind of crime, carrying that kind of penalty, without prior knowledge of the inside. They also usually involve more than one person, and it seems difficult to me that two others could be persuaded by one to just take a stupid chance without knowing what is inside.
In the past, when I was younger and partied and hung out and all that, it seemed these crimes always happened to the people that had the parties at their houses. Those houses got broken into more than not, and houses with teenagers were at high risk too. It may not be who YOU bring into your house, it could be who your KID brings into the house.
Finally, I think it is a bad idea to keep a weapon by the door. They could breach that door and find that weapon before you do. Then they are between you and your weapon. I keep all my junk centrally located and locked up, but usually the M4 stays by the bed when I'm at home and my carry rig is on all the time my pants are.
I didn't intend on wearing my carry piece all the time, even at home, but I was trying to break in a holster and find out how to wear it to conceal right, what clothes work best with it, etc., and I just ended up making it part of the attire. Best thing about doing it is that I never leave without it now, and it is no longer uncomfortable. If you only carry part time, it will never feel normal.
If you don't like that idea you can get a 340PD, a scandium .357 revolver, that is so light you'll forget you have it in your pocket.
Basically, having it on you is better than having it stashed away. When I was younger, I thought about stashing it away too, but then I joined the army and learned dynamic entry tactics and such; after that it didn't look too appealing. If you have to keep it anywhere other than on you, it should be centrally located so that the bad guy isn't between you and the weapon. That should be the minimum criteria.
