We started out to do our standard Sunday Hockessin Route. We had a large group with several new riders--plus disparate riding skill levels. Subdivided the larger group to give everyone a better experience. Both groups encountered road closures in Kennett Square due to the Mushroom Festival and chose very different detours to avoid it. As a result, the "slow" group rode 34 miles and actually returned to Northbrook first while the "fast" group rode 37 miles and did a good deal more climbing. Thankfully no one got lost along the way. No mechanicals or other problems to report.
