Did a little research - The Twin Cities has never been a complete host. In both 1975 and 1982, multiple Minnesota cities hosted games, but also in both years, some games were held in Manitoba, and even Fargo (1975 only). So, there is a precedent for a multi-country host, which is the idea I wrote about yesterday, although it hasn't happened my lifetime (having been born later in 1982). Winnipeg (along with other cities in Manitoba) hosted the 1999 event.
