There are a number of pick-up and drop of points for the Gaper Guide,,, a nifty little device that sits on the dash of your vehicle and plays ‘tourist guide’. There are many auto tours to take with your canine pet, and it first began with the Grand Teton and Yellowstone tours. The GPS guides can be picked up at any entrance to the parks, at their home office, or at one of the many listings on their website. Dogs must be leashed when out of the vehicle.
