A kid from AK wants to spend his month of August in South America for some riding... I was doing some research and I heard that Chile is the best place to go.  I found that Portillo or valle nevado are the best places to ride in Chile.  Is that ture? Everything looks pretty exposed over there.  I was just wondering if there is good snow, terrain parks, fun runs, cliffs and all the things needed for an epic trip.  Anyone experience that area or know of a better place? It looks like its a pretty popular resort so does it get crowded? Cheap to stay for about 2-3 weeks? What are the best options for a trip that long? How much is a pass? HELP ME PLEASE! Thanks...
