Ha. I think I have an even better story. Near Salt Lake City there's something like an island with two roads connecting it to the mainland: one on the north and the other on the south. My plan was to drive to the island via its north road (paved and well maintained) and at sunset leave the island via the south road. I got suspicious when in complete darkness the rather narrow road across a weird desert-like substance of unknown density turned into an off-road trail with rather big rocks on it. I figured that if I kept moving at this pace, about 10 mph, I would get to the mainland in 1-2 hours, which was ok as I was young, full of energy and had plenty of time to waste. 40 minutes later I met a real obstacle: a segment of the road was gone, perhaps it sank into that sandy something, or perhaps someone intentionally made the road unpassable to save drivers like me from an even bigger trouble. Anyways, after entertaining the idea of driving around this gap (I had 4x4), I decided that the sandy substance might be a quicksand of some sort and getting stuck there without a car at midnight would be rather dangerous, so I made a u-turn and at the same crawling speed started driving back. The thing is, whoever was maintaining that island, rightfully decided that it was night time and it was time to close a gates across the only unpaved trail across the island. That would be a rather big problem, and I was even considering to break the gates, but luckily there was a very rocky way around across the bushes, that was quite passable on my truck. So I did just that and kept driving for another mile or so until the road got blocked by some strange luminous sparks, that upon closer examination appeared a herd of bisons. Those bisons were quite melanholic and didn't see anything wrong with camping on the only road, but eventually they cleared the path and 3 hours later I finally left that island.
