to the National Park Service. Your visit to a park can be greatly enhanced or a bit disappointing based often on the rangers you encounter. Most of them work for years to reach a permeant status, have to deal with inadequate budgets and, at least in some parks, hoards of visitors. And the occasional "bison in the car" scenario. Who would not lose their patience at times. I have found them to be enthusiastic, well-informed and really glad to assist you to understand the significance or and the beauty of their site. So, thanks. You do a wonderful job. What grander way to celebrate than a view of the Grand Canyon.
