These signs are clearly posted on the dock, but what's not as clear if you're not familiar with Astoria is that this is also part of the River Walk, so the foot traffic and bike traffic are fairly constant in all weather, and the boards do get slippery. I know.
But the second sign is not warning about wet boards. The cyclist has come to grief in the spaces between the planking. I usually ride in the other direction, where the walk is paved, but it can be fun to ride along the planked part of the walk. I have hybrid tires, which helps some, but I find myself making wide turns and cutting strange diagonals across the decking so as not to get into a groove and end up looking all too much like the guy on the white sign. It can happen.
I took this photo on the wharf at Pier 11 on a day recently that was less rainy than today. The white buildings are part of a working fish processing plant where I took this photo earlier in the year. I don't know where summer went. I never did get back to show the fish processing right along the edge of the River Walk. Maybe next year, OK? Or maybe I'll find a pic in the archives and bring it out on a rainy day.
