There’s a canal that runs near my house, and I drive along it for part of my drive to and from work. The angle is bad, and you can’t see much of it, but it was a sunny day and everything was green. That, and at the right edge you can see that big orange side-wheeled thing sitting in the canal. I think it’s essentially for “mowing” the sea weedy stuff out of the canal when it gets choked up. It’s been sitting there for weeks. I almost never see one in action, but they seem to like to park them along the canal for weeks at a time.
One of your tags should be sea-weedy-stuff-action! I like it. Surely someone would google that term.
