Catraca livre

[Dave Paprocki]

[Catraca Livre] is a brazilian slang which means cultural, social and educational events that are free of chargeou at low-cost.
In portugueses catraca means [turnstile], livre is free. So, Catraca Livre is free turnstile.
This slang was born due to a brazilian website, which informs what is possible to do without money in Sâo [Paulo], Brazil´ largest city ( www.catracalivre.com.br).
It also can be translated into a open city.
