I'd like to just throw this out there and see if anyone is interested. The '13 Chile Challenge was this past February, and was held on a Wed-Sat type of schedule. They have trail rides available from stock capable up to what they call extreme. I think their extreme classification is for serious buggys. From what I can gather so far, it's loosely being planned for the weekend after Columbus day, so that's around October 18th, 2014.
These are some of the best trails in the country and I think it would be fun to go down there and help them keep their trails open. If y'all are interested let me know and I'll send them an email to let them know we have approximately X number of Jeeps interested in attending. Here is the link
to their website, on the homepage there is a link to the challenge website. Look at the challenge website and check out their rules/required equipment etc. and see if it's something you would be interested in. They are very particular about their rules because this event gets a lot of attention and the BLM has a very large presence.
