From Travels of Tug 44. Peeking under a bridge, we see Erie Canal Lock E-30 at Macedon, NY. The 16 foot lift lock looks particularly resplendent with the red painted section on the left. Nobody appears to know why it's painted different than all the other locks. This is the westbound view.
From Travels of Tug 44. In this eastbound view, the gates are half closed.
From Travels of Tug 44. 2014: The red area is now painted bright blue! Nobody knows why, so I'll just assume the Chief of The Lock likes to redecorate now and then.
