At the SeaTac airport, waiting for my flight back to Chicago after spending the weekend hanging out with the family at my parents' house in Olympia, Washington. Found this and a few similar examples on a early morning trek around the nearby fire roads. This seems to be the result of either: 1) an artistic and bored lumber worker, or 2) a really out-of-the-box thinking tagger. Ran across several of these stylized numbers painted onto stumps on my morning photo safari. No repeat of the numbers and they did not appear to be sequential, at least as far as I could tell. Maybe an art project from the local college?
