A little about Feria... back in 1847 the festival started as a livestock fair, but soon evolved into a celebration for everyone. Imagine a massive fairgrounds (like Randall's Island in NY when it holds events) split into two parts. The main part is where you can find the casetas - the enclosed tents that are individually decorated and privately owned by families and organizations. In these casetas, the front room has tables for everyone to eat and drink, but often the tables get pushed aside in the evenings for dancing. The back room is a bar where people can order tapas and drinks - the traditional drink being the "rebujito" which is a mix of manzanilla (local sherry) and 7-Up.
The thing about Feria.... if you aren't invited into a caseta, your options are limited. Sure, you can walk around the streets, watch the impromptu flamenco dancing (actually "Sevilliana" dancing), and maybe find a public caseta for food and drink, but the fun is really started when you are inside. When I arrived to Feria for the first time, I was walking around with my camera, taking in the amazing atmosphere, and I met some locals who I immediately hit it off with. The next thing I knew, I had a rebujito in one hand and a plate of paella in the other, and I was on the inside - a part of the family. I am so lucky to have met these amazing people and can't wait to come back for Feria next year!
The other side of Feria is "La Calle del Inferno" (Hell Road) which is an absolutely massive amusement park filled with not just one but two or more of all the rides and games you can imagine. That means two giant ferris wheels lighting up the sky at night and looking over the entire Feria. And lots of churros!! What I found interesting was that there were booths set up alongside the fair games (like shooting water at a target to make a stuffed animal go to the top first...) where there were fake people crushing grapes and then real people serving vino anejo.
