In 1997 my friends Nora, PeeWee, and I drove out to Glacier National Park and Yellowstone National Park. We were young (18) and crazy, driving the entire way out there. Almost drove off the road in the park we were so tired!
Highlights include searching Lincoln, MT for the Unabomber's cabin. We never found it and later learned we couldn't have found it because it was taken to CA for the trial. Also memorable was our night in the rain in the tent in the middle of bear country, too afraid to leave the tent with water seeping in through the tent seams. Over the course of the night we had less and less non-wet sleeping bag-age. I had to go to the bathroom and had the Simon and Garfunkle song "I am Rock" in my head (as we had only an "island" of dry sleeping bag to share).
Nora brought three cameras with her. One she dropped down the side of a mountain. A second died when it fell into a creek with her. I don't recall off hand if the third made it back or not.
