I wouldn't call it a rivalry persay; rather most sports fans in STL view KC as a bit of a joke. I personally love visiting the city, I really like the cultural stuff, but admittedly when I think of the Wizards or the Royals (and those are the only two pro teams they have, right?).... yeah, jokes. If KC got a WPS team before WPS returned to STL.... that's just salt in the wound. MAJORLY.
