Already some awesome jerseys in this thread too, I particularly like the Chicago and Boston ones I saw.
A few I'd like to see are:
Rock Island, (I've liked the sound of this place ever since I first saw the movie Road To Perdition - figure it'd be a cool place to set a minor league club in my fictional universe);
Willow Falls, (pretty sure this NY town was fictional - it's the setting of an old movie I saw on TCM); and
Jericho, (which I personally think is one of the coolest names ever for a place, and the one I almost always used in my Sim City games back in the day).
A few (I think) fairly unique ones I could use are:
DC,
Vegas,
Jersey, and
Carolina. I just put these up here since I usually use these designations rather than the standard names of the places. Not sure why, exactly, but I have a feeling that D.C. and Jersey are holdover habits from that game Bases Loaded I played as a kid.
My apologies if that's too many, but I think that's all I could think of this time around.
