Rode out on Heritage Trail to Dyersville, 62 miles round trip. These bridges are being built to replace the bridges that were washed away from the flood of June 08. Had to climb and carry bike to get on top, was hoping I didn't slip and crash, down onto the rocks. Beautiful day, started out with hat, gloves and jacket, but removed at 10:00 after only an hour of riding. Hope to do it again tomorrow.
