My daughter told me that they don’t teach geography in schools anymore. That’s sad because that was my favorite subject. The last time that I checked interstate I70-I80 ran basically through the center of the United States as well as the Mississippi River splitting east from west. Use those guidelines and you get four sections.
If the NCAA is going to leave the tournament set with two locations then they should divide the four sections biyearly. There are countless cities or schools that can host and have a successful tournament. The northeast is loaded with places that would draw fans. You have Boston, New York, Philadelphia, Washington DC. If you head west towards the river there are plenty more. Columbus, Indianapolis, Chicago just to name a few.
The southeast is stacked with the Tobacco School area, Charlotte, Nashville, Charleston, Orlando, Tampa, New Orleans, Atlanta. I believe that all of these areas would draw.
The Northwest isn’t loaded like the other areas of the country. However, there is still Seattle, Portland, Salt Lake City, Denver, Kansas City just to name a few.
The Southwest is loaded with various locations in California and Texas, Phoenix, Oklahoma City.
All places listed have direct flights basically from everywhere. So there is no need to play in Spokane, Birmingham or Roswell New Mexico
