USA, Canada / Are there any Polish people in Florida? [311]

If You ever go to St. Augustine there is a Polish Resteraunt there. Also if you ever go to Jacksonville, they have a Polish-American club and EVERYONE that goes there speaks Polish. BTW, I am Polish and live in Florida. Also in Jax, there is a European Deli called The European Deli. The owners are from Belo-Russia and they speak Polish and Russian.
