Almost every day I see a tugboat pulling a mess of some material or another along the Fraser River, ultimately bound for who-knows-where. That's about all you can see from the shore. If you can arrange to get an overhead view you can see considerably more, such as the bulldozer thing they've got along for the ride. As it happened, one of those tugboats passed under the Pattullo Bridge while I was crossing it over the weekend, heading west along the river.
I gotta wonder what that grey stuff is, and how much of it ends up getting washed back into the water.
