I really like this track! I hope you'll like it too. You need to reach power gear to have a competitive time of course.
This is the text about the Quilmes:
"The Quilmes people were an indigenous tribe of the Diaguita group settled in the western subandean valleys of today’s Tucumán province, in northwestern Argentina. They fiercely resisted the Inca invasions of the 15th century, and continued to resist the Spaniards for 130 years, until being defeated in 1667. Spanish invaders relocated the last 2,000 survivors to a reservation (reducción) 20 km south of Buenos Aires. This 1,500 km journey was made by foot, causing hundreds of Quilmes to die in the process."
