In some ways I prefer to visit other stadiums when I'm neutral (or largely neutral) on both teams. That way I can focus more on what's different about each ballpark instead of solely on how unnecessarily dramatic the Brewers are making a game. At Progressive Field, be sure to check out Heritage Park beyond center field, featuring the Indians Hall of Fame and other historical goodness. I'll add that when we visited Progressive in 2009, I wore a Brewers hat and Branyan shirsey (Russell was playing for the visiting Mariners that day) and multiple people, fans and employees, remarked favorably on my Brewers fandom. One employee thanked me for hosting that snowy series in 2007 or whenever that was. I didn't have anything to do with that, but saw no value in pointing that out. Have fun!
