Sandra and I were in Redding, CA for the 15th National Trails Symposium sponsored by American Trails. We took advantage of an afternoon break to bicycle on the Sacramento River Trail making a loop to the Stress Ribbon Bridge and back. At the Symposium a model of the planned Sundial Bridge was displayed. The bridge was opened in 2004. I was back in Redding in 2016 to bicycle both the Sacramento River Trail and the Sacramento River Rail-Trail. I had the opportunity to bicycle across the Sundial Bridge. Very impressive.
