Joseph is really into elevators these days, so we visited Seattle's tallest building, Columbia Tower, with its 76 floors. There's an observatory on the 73rd floor, but I wasn't spending $15 on looking out the window when there was a perfectly exciting (and free) view from the Starbucks on the 40th floor. We did ride the elevators up and down a bunch of times. Building security must have thought we were nuts. The building from the ground.
