  • Dressed in the early 1900's fashion with a contemporary feel, 110 women preform in front of the Flatiron building on 23rd Street where men also dressed in period piece costumes watched as they lifted their skirts and ran away on June 21, 2012. The performance comes from a legend where it is said that due to the angle of the building, when women walked down the street wind would blow up the women's dresses revealing their legs which caused men to linger around and watch. The legend goes on to tell of local Authorities using the code word, 23 Skidoo, which told the men that they had better scam from the area. (Benjamin Chasteen/The Epoch Times)

  • his undated handout image provided by NASA/JPL-Caltech/University of Michigan, shows The Four Corners area, in red, left, is the major U.S. hot spot for methane emissions in this map showing how much emissions varied from average background concentrations from 2003-2009 (dark colors are lower than average; lighter colors are higher. Satellite data spotted a surprising hot spot of the potent heat-trapping gas methane over part of the American southwest. Those measurements hint that U.S. Environmental Protection Agency considerably underestimates leaks of natural gas, also called methane. In a new look at methane from space, the four corners area of New Mexico, Colorado, Arizona and Utah jump out in glowing red with about 1.3 million pounds of methane a year. That’s about 80 percent more than the EPA figured and traps more heat than all the carbon dioxide produced yearly in Sweden. (AP Photo/NASA, JPL-Caltech, University of Michigan)
