These images are from a recent photo trip to Olympia. We walked around the various alleys and loading areas. There were a mix of levels of graffiti. The downtown area was very much run down and semi-deserted, due to the lack of workers in downtown buildings. The result has been the closure of many retail spaces that made a significant percent of their business from the lunch crowd.
This was a bit of a puzzle. But I expect that someone left the steel door retracted and the tagging took place.
My guess on this area is that the owners/tenets make an effort to keep the area freshly painted each time additional tagging takes place. That is one approach. The other is to hire murals painted. This approach works most of the time, and some of the future blog posts show some of the murals of downtown Olympia.
