reports Greg arranged for the scoreboard to run the message during the fifth inning.
According to The Great Falls Tribune
, Greg's mother Cathy said he sent Erica to get beer during the Chicago-Pittsburgh game so he could arrange for nearby spectators to videotape her reaction when the scoreboard says "Erica will you marry me?" But unfortunately, Erica took longer than he expected and missed the proposal on the scoreboard.
Watch Greg's reaction when the message appears but Erica wasn't in sight.
