The Brooklyn Reality tour was based upon a Seinfeld episode and only covers certain areas of Brooklyn - the parts the tourists don't see and where natives actually live (versus those who moved into NYC/Brooklyn)
The Catman Do was something completely different. The soup Do sorta replaced it an always takes place the night before the BRT.
The Wine Do is fairly new (compared to the other 2) and always takes place after the other two.
Not everyone attends all 3, and technically, it's not a weekend event. They're all individual.
