Now that's pretty freaking random

As thoughts go, this one was more random than most. I was driving across the Potomac River this morning (on a bridge, of course) when out of nowhere I wondered, how many rivers have I crossed without benefit of bridge or boat? At first I figured the answer was "Damn few," but after a few moment's thought, I realized it was probably more than most people. For the record, the rivers I have crossed under my own power without benefit of any spans or floatation devices include the New River in Virginia, the Firehole River in Wyoming (in Yellowstone Park), the Fu Lung River in Taiwan, and the Saluda and Broad rivers in South Carolina. There might be more. I'll have to think about it.
