I'm always intrigued by images painted on streets. We have a "breadcrumb trail" up and down both sides of the Astoria hill indicating the way to get to the Column at the top. This image on 7th Street is pointing to the right, because at the intersection with Niagara Avenue just ahead, you turn right to go on up the hill toward your destination.
What's really strange is that although I'd walked or driven to the Astoria Column many times, it took me forever to realize what these odd symbols were about. I suppose it looks like a column once you recognize it, but I kept wondering if there were some mysterious fortress I hadn't heard about. I hope the tourists are smarter than I was. Once you've been here long enough to recognize the images on the street, they are superfluous. However, I like looking at them and feeling proud that I know what they are :-D
