Why did we leave Capistrano?

Out in the snow today headed for Port Huron... I thought the roads were going to be worse than what they were so I left early. I came upon this tree during the heavy snowfall and noticed a group of swallows hanging out... They did not look very happy to be in good ole Michigan.... I was able to walk right up to them and photograph them and they did not even budge.... Lighting was very challenging.... Click to enlarge
