Grand Teton National Park in northwest Wyoming will alter some road traffic and parking in order to accommodate an expected influx of people looking to view the total solar eclipse on Aug. 21. "A typical August day is a very busy day at Grand Teton National Park," park spokeswoman Denise Germann said. "This Aug. 21, the day of the total eclipse, we're expecting to be the busiest day in the history of the park," Fees will be waved at the Granite Canyon, Moose and Moran entrance gates to ease the flow of traffic.
