The Tubes is the most common name for this trail, but there is technically not a "signed name" or official trail name. It is blazed green (which I think is already included in the relation). The official Shenipsit trail takes a road detour around Rt2, but the Tubes trail is the most commonly used cut through to avoid the long road detour by going under Rt2 instead of around it. I would be of the opinion of keeping it in the name, but since its not technically an official name, feel free to change the name if you think its better for another field. I think the naming convention for trails on OSM is a bit inconsistent anyways, and I previously had another user become upset when I added the official names to trails already mapped as relations. Even though there are some very popular major trail systems in NE where I have seen the trail names included under both the individual path name field and relation name, so not sure why its ok for some areas but not others. Maybe smaller CT trails arent popular enough to be named in both places?
