Headed out for a 40 mile rid this morning. Planned to head south on Rt. 27, but after 3 miles hit a detour sign. Rode another 5 miles and tried to get back to Rt. 27. It was still closed, and a parade was heading down the street. Watched the parade for a few minutes, then planned another route. Got to Natick center and found more parade/festival to be avoided. Final got past all that by riding on Rt. 135, 16, 115, 126. Final tally: 40.7 miles in 2.5 hours. Great weather this morning, now starting to rain.
