Corona Arch near Moab. The trail was very, very busy due to the park closures resulting from the US government shutdown. For two weeks our plans were ruined and we were particularly annoyed with the way the shutdown was enforced by those rangers who were working. Being turned off a BLM campsite which only provided a space to park and a long-drop toilet was completely unnecessary. Nor were we offered a refund for the nights that I had paid for but lost.
