Yesterday, I walked through Pioneer Courthouse Square and realized it was time for the Festival of Flowers. I couldn't figure out what the design represented or if it was finished, until I saw the banner that identified the theme as 'Tattoo Portland.' Then it all made sense.
There are tables and chairs among the flowers, so I pulled up to one and did this quick sketch,
without being hit by the pigeons swarming above or the intermittent raindrops.
Here's a photo where the theme seems pretty clear.
You might want to check it out and make a sketch. Those chairs are much more comfortable than the bricks.
