I used to live in Orlando and moved to Miami when I turned 18 (3 yrs ago) I didn't know anyone here so here's what I learned, Miami is: high crime, lots of haitians cubans and south americans, african americans, europeans, a lot of rich people, a lot of poor people, a lot of homeless people, rude people, hot chicks, lil wayne, nice weather, drugs, lebron james & dwayne Wade, tall buildings, guns, mansions, ghetto, pitbull, parties, unemployment, sex, steroids, hurricanes, beach, food, banana republic, worst drivers in the country, . if you don't speak english you'll do even better.
I love Miami, there's a lot of good things and bad things about it.
