The location of the Commemorative at the Commemorative on Saturday morning at 9:30am has changed because of weather.
The new location: Boott Cotton Mills, 115 John Street (just a block away from the park).
After crossing over the canal, walk into the Boott Mills complex and turn right. At the end of the courtyard, enter the door at the far end of the building (southeast corner). Take the elevator to the second floor.
