DIA has been a nightmare with the storms. I knew a lot of people trying to fly and having to wait for an available seat on another flight because theirs were cancelled. When this happened last week, DIA was actually completely shut down for a while...people were camped out there, some for several nights. There were a lot of pissed off travelers.

DIA is out on the right side of this photo, where Denver is toward the middle. For reference, I included a tag for Golden, where you can see the mountains up next to it:
edit: I hope it was okay to post images in an already started IOTD thread. If not, I am sorry. Let me know.
