This video is up on ESPN Chicago showing Wrigley getting ready for the game on Saturday. (Full Article here)
I live two blocks away from Wrigley and plan on going around the stadium each night this week and then to GameDay Saturday morning and possibly the game Saturday (from scalpers). When I went by last night, I did notice a lot of purple trim, but I didn't realize the main Wrigley sign had turned purple. I also tried to peek in the gates on Shefield, expecting to see this.
Nope, all I saw was the back of some padding. Also, I was surprised to find out the field is going East and West instead of not north and south like I have seen in old pictures.
I will continue to update as I hear more.
