You have to wonder what planet some folks live on. A Colorado sheriff posted a Craigslist ad to sell his old, personal vehicle, and a potential buyer (39-year-old Shawn Langley) responded to the ad and offered to pay with four pounds of "home grown black-market" marijuana instead of cash. Teller County Sheriff Jason Mikesell says Langley then sent photos of the marijuana via text message. Miskell had undercover detectives meet with Langley, who showed up with a companion and two large bags of marijuana. Both men were arrested. (UPI)
