Jaistemay Marquez (17year old kid) ran the bigest waterfall 75/80 feet in Micos (Jorge Marquez)

Sunday 25 January 2009 Jaistemay Marquez a 17 year old kidd
complete a great  achivement  when he ran sucsesfully  "El Toro"  the bigest waterfall down in Micos SLP Mexico 
This waterfall  is about  25 meters high ( around 75/85 feet) 
the  line that Jaistemay  run was the far left one, over the reactive wave, the same  beautifull line that Pat  Keller and Laurence Simpson 
fired up a year ago by the very first time.
Any way Jaistemay  is the first Mexican how run this waterfall  ever, and at the same time the yungest American as well.
