Seriously? Not that "Twins Territory" is a well defined concept, but I would bet their marketing people would include Iowa. If you go by radio stations, you can get the Twins out of Mason City, Spencer, Iowa Falls, Cedar Rapids, and Des Moines. That's a lot of Iowa. The fan base has also most certainly been on the rise here in eastern Iowa. First because of the Twin's recent awesomeness, but also because the single A Cedar Rapids Kernels, which the Twins took over in 2013 and are a very successful minor league operation. Prior to that there was no Twins radio in most of eastern Iowa. Mason City may well have been the only signal. Most TV packages in Eastern Iowa carry Chicago regional sports networks, but my sense is that Twins fans rival Cubs fans from Iowa City northward.
