I spent Saturday canoeing the San Marcos river with my son and a friend. The section we paddled was a narrow, gentle river that wound its way past high sandstone banks, through cattle farms, and past some big houses. There were enormous cypress trees, herons, red-tailed hawks and a bunch of turtles who were enjoying the sunshine. The water was cool as it’s spring-fed, so we spent about an hour swimming in a big pool. It was my first time paddling Texas water, and we all had a great time.
