The ongoing mural tour heads back to central Vancouver, WA, near W. 20th & Main St., where a gap between a couple of buildings has been transformed into a twee little garden spot. There are a few benches, some flowers, and a large mural on the side of the Main St. Day Spa building. The Clark County Mural Society's mural map doesn't list anything north of 19th, so I don't know the story behind this one.
I suppose the map ends where it does because this area isn't considered part of downtown Vancouver. My VanWa geography is kind of hazy, but I gather the business district along this stretch of Main St. is called "Uptown Village", and the city's neighborhood office says Main is the line between the Arnada and Hough neighborhoods. So now you know as much as I do.
I have a sorta-theory that Portland's next hip (and hyped) area is going to be around the historic mini-downtown of one of the 'burbs. People are increasingly being priced out of Portland itself, and demand is such that whenever a new part of the city becomes "trendy" it instantly fills up with cookie cutter luxury apartments. So maybe it's time to ask which suburb gets to be the Brooklyn to Portland's Manhattan. Vancouver has to be a leading candidate, although it loses points for the commute into downtown Portland.
