Is it a prank or a political statement? Xcel Energy customers in Boulder have been getting letters warning that their power will be shut off. Xcel says the letters are fraudulent but they’ve drawn a lot of phone calls from worried customers. The letters have the Xcel logo, an actual Xcel number to call, a little slogan, and all the little things that would make them seem real. The problem is happening in Boulder where someone is slipping the letters under people’s doors.
