I have seen insanity and it happens on the streets of Valparaiso, Chile.
The Valparaiso Cerro Abajo Race is a legendary urban bike race and is
more extreme than skydiving out of an exploding F-18 piloted by Charlie Sheen - while chugging a 2 liter of Mountain Dew. The rider must brave jumps,
stray dogs, and flights of stairs along the steep downhill path. The
first person perspective provided by the excellent helmet cam lets us
take in every glorious and frightening detail. Do yourself a favor and
watch this one in full screen mode.
