I've always wanted to use a Peregrine (falcon) mascot for a team, as they're the fastest flying animal on the planet. Something like 122mph on a dive bomb. So, in a sport relying more and more on velocity, it makes even more sense. Looking around for information on Baltimore, to avoid using the traditional "Bay Something ..." nickname, I saw that peregrines were common to the area, and the Baltimore Bombers made their entrance into NABO.
Originally in the '24 version I had some other smaller regional teams, but for the '26 version, I used the 48 largest metro areas in North American, except for Riverside/I.Empire, CA and some cities in Mexico as those areas already had multiple teams.
