One summer, I worked as a CIT at a Catholic-run camp in the mountains outside Santa Fe. It was mostly about having fun and was very non-churchy, if you know what I mean.
We did a "Christmas in July" for the campers and some kids of the folks who lived near the camp. We decorated the main mess hall, had a tree, little presents, etc. Storm clouds moved in over the camp and a light rain started. As it fell, the Sunlight caught it. The kids thought it was snow. It was so cute.
