Pup-- Thanks for the resource! Maybe we can talk routes on here/PM? Let me know if you have suggested tweaks to the routes. I picked the cities I did because most were a mix of smaller cities along with a few "landmark" larger, cultural cities (Chicago, Denver, New Orleans, etc) and I wanted each to end with a big, climactic city like DC, Miami, or New York. 

Zee-- Be aware, depending on what our players pick, we may not end up seeing New York, but I'd love to hear your ideas. Like I said, you guys helping me shape this world will be a huge factor in how fun this will be.
