I'm digging owbc's idea to play up the rivalry. It ain't goin' away. Might as well have some fun with it. They could produce some video board content for these series, "The Cubs Fan's Guide To A Real Ballpark". Do it in the style of the pre-flight videos where the flight attendants show how to use flotation devices. Show Cubs fans how to use non-trough urinals, how to not spill beer on small children, how to assess whether a fly ball may or may not be a home run, and so on. Playing up mutual contempt for the Cardinals might be fun, too. We do have some common ground.
