Sorry, Wrigley lover here. I remember as a kid walking up the ramp into sunshine, seeing the ivy and the players. All good memories. I'm not a big fan of skyboxes, retail stores, hotels etc.
Just thought of something wasn't it in the 60's or early 70's that they added the fence thingy on the outfield wall to keep the bleacher bums from running on the field? Hmmm, could it be that Wrigly has a longer history of such stuff?
