I vote for calling the police and reporting it also. If you say you aren't even sure the police know there is a road/houses where you live - make sure they know in case of emergency. A motion sensor light would be a deterrent also - they have cheap solar powered MS lights online. Good move on your part taking the keys out of everything and hiding them also. We have guns and dogs at our home also but in my personal opinion, I would use both as a last resort because I would never point a gun at someone unless I was going to use it - you never know what they are carrying and could shoot you first - particularly if they are drunk or hopped up on something. I think the laws around here at least are very specific about shooting someone, i.e., have to be IN your house not halfway through the window, etc. or you yourself could get in trouble even if you are the innocent victim. If you do go the gun route though, remeber that a shotgun is more effective than a handgun (IMO) as it has a larger "pattern" with the shot and you don't have to be as precise in your aim at your target...Whatever you choose to do, just stay aware and please be careful.
