|My sister, Cheryl, flew in from Philadelphia to visit for a week, a nice birthday present. She stayed in Estes Park in a wonderful cabin in the woods. We traveled through Big Thompson Canyon to visit her, Estes Park and Rocky Mountain National Park. A pile of rocks in front of her cabin was the playground of a large family of chipmunks which entertained us when we visited. We had a nice cookout on the grill which the chipmunks seemed to enjoy also.
