We will be travelling to the U.S.A on 9th October we are doing a guided tour of the parks and have read in the paper's in the U.K that the parks had turned away tourists because all of the rangers are not at work does that mean we will not be allowed into any of the parks we are visiting Yosemite , Bryce, Monument,Grand Canyon, Zion, the only place we know there wont be a problem is Vegas.
