Hab ich auf der Facebook-Seite von Arizona gerade gelesen:
"Next weekend, August 14-15, is the third, and final, fee free weekend in
America's National Parks for 2010. For those two days, more than 100 of
the parks - including Grand Canyon National Park - will open their gates to the public at no cost, giving
visitors a chance to experience "America's best idea" for themselves."
