Kraig's given you some great advice, as usual. But you sound to me like you've pretty much got a handle on your procedures. I clear my own property every time I come home from anywhere if I've been away for more than a few hours. But also like you, this is only if everything appears normal-if anything is obviously amiss, the police will get called and I'll watch from a distance. My flashlight is a RayOVac Sportsman Extreme, C-type, so it's fairly small, 180 Lumens high and I believe 75 on low. Cheap, and quite well constructed.

I am the weapon; my gun is a tool. It's regrettable that with some people those descriptors are reversed.
