I live in St. Petersburg FL. Most folks that move here are from the mid-west...Ohio, Nebraska, Chicago, etc...and the cycling here is great. Folks are very friendly in general. I recently toured central Florida for a week and met nothing but nice folks. Miami area though...most folks there are from the Northeast...NY, MA, etc...and they bring their attitudes with them. I've had friends move to Ft. Lauderdale (near Miami) and actually ended up moving back because of how rude people there are. Miami is full of shallow people who think they're big time for some reason. There's some REALLY bad parts of Miami too.
I'm originally from NY so its not a knock on Northeasterners.
