Hey, it's a twofer! Some indication of the crowd last Saturday. To get a better sense of it I'd have to find an elevated position to shoot from.
For locals, the first one is inside Luther Ely Smith Park, between 4th Street and the new entrance to the Arch museum. The second is looking east on Market Street from about 7th.
As you can see, the weather was perfect. It's been unusually warm for several days but winter is back today.
