Helmets are required. There is a possible off-road alternative on a future section of the trail for those with fat tires, if the ground is dry enough. Heavy rain will probably cancel, but last year, four of us rode the trail through a Nor'easter. Email dmink@massbike.org if you intend to come and want my home phone to see whether the ride is cancelled. As of April 5, Accurweather is forecasting a temperature in the 40s for Saturday, with 20 mph winds, but no rain.
If you can't make this ride, There will be another ride up the Neponset starting from Castle Island in South Boston on Sunday, May 16 for Bike to the Sea as part of Bike Week.
