Kudos to Bob M and Kevin for opening the putin at the Knights of Columbus in Tewksbury!
There was a tree 150 yards upstream of KC blocking river. Kevin and I cleared it today 6-10, opening a 3 foot wide passage on south bank of river, We left a couple of branches to help friends pull through gap. Way to get through going upstream, go under tree on right then cut across rive to new gap (-6″ deep) on left bank. Going downstream is pretty easy passage.
