Based on the experiences shared in this thread and past similar ones, it sounds like the #1 thing the Brewers could do to improve the Cubs/Brewers fan ratio at Miller Park is to crack down hard on excessive drinking and poor fan behavior. Too many people are having their experiences spoiled by rude and/or intoxicated fans. Perhaps these games need to have cheering sections where only Brewers fans are allowed. The other thing (which will be unpopular) is to discourage reselling of season tickets for profit. Maybe this can be done is a positive way such as giving rewards to season ticket holders who show up to the Cubs games or giving season ticket holders the option to be relocated into one of the Brewers-only sections. Here's another idea--the Brewers can re-frame the entire 'rivalry' thing and have a direct marketing campaign to encourage Cubs fans to come to Miller Park--and convert to Brewers fans. The Cubs--Ricketts in particular--have basically priced a large segment of their fanbase out of their home ballpark, encouraging them to attend road games instead. The Cubs depend on the Brewers to keep this segment of fans engaged in the ballpark experience. They need us! The Brewers can sell their ballpark experience--want to cheer on your favorite team in the convenient and affordable Miller Park? Why only come for Cubs games? Be a Brewers fans and enjoy it all the time!! I don't know if it will actually convert anyone but I think it would send strong message regardless.
