Heh I like the spraypaint part of that plan, aside from having all ur mates waiting in the dark, cold confines of the driveway on a nightly basis... seriously tho, the guard dog idea is great, not only do they protect your property and your personal safety, theyre also great companions and friends... if you can have pets at your location, a big ass german shepherd or red heeler would be great... and tho some people might laugh, Corgis make excellent guard dogs too (trust me, theyre a medium sized dog with short legs, they >can< bite really hard).
Still, the idea of spraying a would be thief with fluro orange makes me chuckle..
