Groups from all over Bolivia come to dance.

Just to give you some background, thousands and thousands of dancers come into Oruro, and ontop of the spectators, it triples the normal population of 200,000 people. The dancers start practicing and working on costumes in November. The parade route is 8 miles long and they dance 2-4 times along that route during carnaval. We saw some dancers in high-heels limping over to the side and thier support person sprayed some kind of numbing novicane on their feet so they could keep going. The costumes are expensive and "sponsors" help finance the groups expenses.
