Then we went for a bike ride on the dirt road that basically followed along the creek, with the possible goal of checking out the ‘periodic spring.’ We asked some people heading back (in their truck) about the hike to the spring, and they indicated it was only moderate in difficulty, but not suitable for me in my flip-flops. (I had injured my left foot a week before the trip began and was trying to avoid my tennies if I could. And some days I couldn’t have worn them if I wanted to because of the swelling in the heat.) Oh well, the ride was nice anyway, and we saw two small hydro-electric power plants along the way.
