I’m planning a trip to Yellowstone next September and have all my stops planned out. As others have mentioned, Google Earth is fantastic! Street view and a view from space. Once I get into Wyoming from South Dakota, even if I have to stop after only 150 miles or so, I’m stopping. The last thing is want to do on a lonely two lane road is run out of gas.
I have a large Rubbermaid tub that I normally keep my firewood in but for this trip it will be holding three, five gallon cans….. just in case.
