Forum:Where is the "tri-state-area"?

So, from my staring-at-a-US-map-all-day time, I want to list all the potential TSA's this can take place in, assuming they still use the same state borders as our world. I mean, Germany is called Drusselstein, so I don't know. There are: Washington-Oregon-Idaho, Idaho-Montana-Wyoming, South Dakota-Nebraska-Iowa, Michigan-Indiana-Ohio, Pennsylvania-New Jersey-New York, Nevada-California-Oregon, Texas-Oklahoma-New Mexico, Arizona-California-Nevada, Mississippi-Arkansas-Tennessee, Mississippi-Alabama-Tennessee, Alabama-Georgia-Tenessee, South Carolina-North Carolina-Georgia, Kentucky-Tennessee-Missouri, Nebraska-Kansas-Missouri, Connecticut-Rhode Island-Massachusetts, New York-Connecticut-Massachusetts, New Hampshire-Massachusetts-Maine, Wyoming-Utah-Idaho, North Dakota-South Dakota-Minnesota, Wisconsin-Iowa-Minnesota, and several more. I only just now realized just how many tri-state areas there are.
