Lake Freighter Entering Harbor

Muskegon is a working port. I caught this lake freighter entering the harbor at sunset on a June evening in 2015. They sound their horn when entering or leaving a harbor. While searching for a link to freighter horn meanings I found this article. What a headache:https://www.kansascity.com/news/nation-world/national/article225937580.html Have a lovely weekend!
