Saturday - Gasparilla!
For those who don't know, its rated to be one of the biggest parties anywhere. Every year there are about 1/2 a million people outside, partying, 3+ live concerts, a 5 hr parade like Mardi Gras (boobs and all), revoked open container laws etc. House parties for about a 10 mile square area in Hyde Park tampa....
