I'm a little paranoid about my stuff, but a strange vehicle in our neighborhood will usually have its make and license plate number noted by someone. My address - Upstate NY, my last name - there are a couple folks here who know it but for the most part, the folks here are like my neighborhood so I really don't have too much of a problem with the regulars, it's the unknown lurkers. My car - well unfortunately, it does stand out among the SUV's, menopausemobiles and econoboxes in my suburbia neighborhood - but I don't often leave it in the driveway for more then a very few minutes. I do have a monitored alarm system and display window stickers that say so. I back up to a woods that eventually goes to a busy road then an interstate. Neighbors on both sides of us have been burglarized. And yes, I do have several very loud, fairly long devices that when a certain lever is pulled, a pointy thing or many round balls comes out of one end - and one of those devices is always ready, 24/7, to make noises.
