After crossing Lock 21, which is a functioning lock that raises/lowers boats traveling to or from Oneida Lake, there is a short roadwalk. Then the trail crosses Route 46 and rejoins the old towpath. This section is better than some, but there is only the old canal and a narrow strip of trees between the trail and the state highway, with passing vehicles and homes easily visible.
We had zero snow at home, not even sorry little mounds along the roadsides, so I was surprised to find it here. Temperatures were in the mid-30s, with both rain and sun, and lots of wind, so I adjusted layers frequently. The blue sky was an unexpected but very welcome treat that lifted my spirits enormously. We don't get much sun here this time of year.
