Don't ever trust a cold call, especially if it's from "Vegas, baby". This town has more crooks per square mile than anywhere else in the world, and each one has a different reason for their felonious or larcenous nature. I live here, I should be immune to it, but I have been burned a couple of times, by some of the most sincere and honest looking folks you ever saw. Tends to make a feller a bit skeptical.
