It's me, the insane one! Look, I guess this is a "to each their own" thing. I can't drive 1 -1.5 hours in any direction and find large pockets of first generation immigrants. I'm certainly not saying they don't exist in the entire state. Of course they do! But where I've lived in the past, this is what the communities were made up of. FL isn't like that because so many people aren't from here originally.
My area has a yearly Indian festival, Greek festival, Oktoberfest, and an Irish festival. The Greek festival is very authentic. It is held at a Greek church and is a great time. However, again we don't have Greek neighborhoods. There isn't a pocket of Greek restaurants and stores and neighborhoods with mostly Greek families. The Indian festival is a revolving festival. It moves around the state of FL. Some of the very same people that are performing here will pack up and go three hours away to the next area. It's like the old time parking lot carnivals. We do not have a heavy Indian population. We do have one restaurant and one store, but the festival itself is so-so because it really doesn't pull in many Indians to give it the right vibe. The Irish and German festivals are simply an excuse to drink beer. Nothing wrong with that, but it really has absolutely nothing to do with the culture itself. They'll bring in a couple groups of local dancers to perform some traditional dance, but it really is about the party and beer.
I don't live near Miami. I would certainly expect events like Goombay and Carnival to be huge in Miami.
Orlando is a large metropolitan area. There is a fabulous Indian store and three Indian restaurants within walking distance to one another. But once again, the area isn't full of Indian culture. There is a Home Depot, though! There is another area that is intermixed with very traditional Asian grocers. It is definitely an authentic vibe. I am not aware of any type of regular festivals that they hold.
For me, FL will never offer what I am looking for in those terms. That's okay. I can't imagine there is one single place that will offer anyone absolutely everything they ever wanted. It is a big negative for me, but it isn't a deal breaker.
