I heard on the radio that there was an internet rumor going around that all Maryland gas stations were closing at 4pm today and not reopening until Tuesday. I guess people bought into it and ran out for gas. The governor's aide had to go to the media to tell people that it was bullshit. Perhaps by then the damage was done. I doubt it though.
