Fall Weather Chin-ups

We've been enjoying some beautiful fall weather. Today the temperature got up into the low 70's. It was so nice and warm in the park, with just a light breeze to shake the leaves, sending many of them fluttering to the ground. People in our neighborhood park are taking advantage of the weather by soaking up the sun. This guy was doing exercises on the lawn. Between sets he would lay out on a towel and do some sunbathing. In this shot I managed to catch him doing chin-ups from a tree branch.
