Having grown up in southern California, I don’t think I ever really appreciated spring until I moved to a part of the country with a real winter. It was only a few weeks ago that it was finally warm enough outside for me to open the windows in my apartment. That’s probably my favorite part of spring: the first dose of glorious, fresh air. I thought of the chimpanzees and how it wouldn’t be long before we would be able to open the barn doors in their playroom and let the warm air in. As Jackie said in this post, that opportunity came just the other day, and the chimps seemed to be just as grateful as I had been. Here’s some video from that day.
