For a $50 donation to Cubs Charities, guests got to play catch and run around on the venerable field, which hadn't hosted a football game in 40 years prior to Saturday's Illinois-Northwestern match-up.
Sunday's fun was an all-ages affair, and a nostalgic trip through the years for longtime Chicago sports fans.
" Watching on TV last night and now having this opportunity is just-- you have to be a lifelong Cub fan and Wrigley Field fan to understand what it means inside," said Katherine Nakis.
"For it being part of a charity, it's really a good thing to be out here. Lot of fun," fan Scott Motisi said.
Despite the controversy over the east end zone not being used for offense in Saturday's game, many fans say Wrigley as a football venue was a good idea.
