You can get some pretty cool stuff on, but it may be a bad place to score some weed.  A New Mexico woman found this out the hard way.  I think it was pretty easy for authorities to figure this one out, an ad on the popular classified site titled "New in Town looking for Mary Jane".

Reuters news agency says, Anamicka Dave, 29, of Roswell was released from the Chavez County jail on a $5,000 bond, and faces one felony count of criminal solicitation of marijuana, authorities said.  She was arrested by undercover officers in the parking lot of a local business after a narcotics officer surfing the Web on his own time spotted her posting.  Wow, this chick seems really stupid and it only gets dumber!  When the officer first saw the posting, he thought it may be another law enforcement agency running a sting, but it really was an idiot trying to get her buzz-on by looking on craigslist.  Genius!
