What is a piquete?   Groups of people block streets and highways. This activity does not present any danger to the visitor. The only inconvenience that may arise is that tourists should change their tour circuit, since the streets may be blocked. (Tourists may take advantage of the situation to see monuments and get acquainted with the distinctive characteristics of some inhabitants). It is convenient to be informed on the possibility of a piquete when you have an important time schedule, such as the departure of your flight.
