Lake Quannapowitt Directions
For the Comverse launch, take Exit 39 (North Avenue) from Route 128/I-95, south towards lake. A quick left onto Quannapowitt parkway and pass both office buildings, swinging behind the Comverse building.
For the "Wall," take the Rte. 129 exit south from Route 128/I-95 and follow the road around the lake. Look for a small (very) grassy area with a park bench about halfway down the lake.
