This weekend, there's a u-pick "pumpkin patch" (11am - 2pm) in front of one of the Amazon buildings.
A lovely decorated truck, a few vendors, hot cider and cocoa, loud music.
Organized by SLU.
I went there Friday a little too late, and all the pumpkins were gone, very deserted.
On Saturday, I arrived at 11:50, not many pumpkins left. Yes, I picked one.
The stairs got some new painting. Autumn-themed.
