Hello,
The schedule for the amusements appears to have changed and it looks like it will no longer be open tomorrow. Instead, we will do a ride from the same start location and time but go to the new Gronk playground on the esplanade instead.
Essentially the whole way will be on protected bike infrastructure of Cambridge, Watertown and Boston. The distance will be about the same going there, but for many people on this email list who might come the ride home after will be shorter.
FYI Gronk playground has a water feature in case you wish to bring water clothes.
