When camping in Colorado, especially in May, we have found some interesting extremes in weather. We did not have snow over Memorial Day while camping in the Mount Evans area, but some fairly hard rain made life interesting. One highlight was observing some campers in the next site over from ours. They did not really have a clue how to pitch a tent so as to prevent rain from getting inside. Funny how a tarp can actually work like a funnel. Anyway, they eventually gave up and left. We played cards or something.
