I don't know if it was explicitly Cardinals territory, but I don't think they would have demanded fees. How they could keep a rivalry in Minneapolis and Houston, I don't know, but what I do know is that 1). The OTL date is 1958, not 1956. 2). That the Giants would move into the Metrodome and the Dodgers would move into the Astrodome (or the Dodgerdome, or the Dodgedome, which would be funny if Chrysler Corporation tied it in, sparking the trend of naming rights earlier than OTL [1970 for Rich Stadium]). They would probably also get new ballparks in the 1990s, in Houston it might be called Dodger Stadium and in Minneapolis maybe Target, Best Buy, or some other company based in Minneapolis-St. Paul could get naming rights.
