Rushmore to Fishing Bridge - Yellowstone

Here's a video of Fishing Bridge. It's not a parking lot.... it has trees. :) If you need hookups it's the most convenient place to stay. If you don't need hookups there are many other campgrounds in the park. We've stayed at Mammoth, Madison and Bridge Bay.
