An earlier post describes some differences between the Carnival in Rio and its smaller counterparts in the pre-Lent celebrations elsewhere in Brazil.
This post describes the event called “Carroça” in Rosário, named after a cart and sometimes used for what in U.S. English is called a parade “float.”
Here the carroça can also have its original meaning — as a donkey cart. This you won’t see in the Rio parade of floats.
