Marlin, thanks for posting that. I printed it out for future reference. I need to recheck the actual Colorado regs to see if there is a specific provision against carrying in banks and post offices. If there is, as the lawyers say, the issue becomes moot; if not, I probably wouldn't chance it anyway, but it's still nice to know what the law actually is. "Ignorance of the law is no excuse," or so goes the legal maxim.
