We are so inexperienced about the National Parks!. We are retired and just got our Park lifetime passes. (#1 checked off our "to do" list) and are planning on driving from SF BAY AREA to Yellowstone, Grand Tetons, Mt. Rushmore, Black Hills.in a few weeks. We have no reservations and have just purchased guide books and will begin our planning immediately. Our timing I know after reading posts is really bad, and to top that....we are traveling with a 7 lb. toy poodle. She is a service dog. (trained hearing dog with her jacket, creditionals, etc.) so we know legally she can go on leash and stay anywhere. But, we prefe to go where pets are allowed as not to offend and have to show papers, etc.. Can someone give us some suggestions PLEASE!. So far, we will spend first night in Winnemuca, NV., then Pocatello? or Idaho Falls,? then should we try to stay in the park? or in Gardiner? As you can see....we are the true "innocents at home" as opposed to innocents abroad so we need your help!. Obviously we are "seniors"!.
