The countdown begins, I think IIRC you have 90 days to enter Brazil once you get your Visa. I think I would go ahead a do a border run while you are nearer Brazil in Boliva or Peru so you don't have to worry about crossing over in time when you are way down South. Once its validated with the first crossing you are good for 10 years
I was ready to go home in early June but still had to go to Brazil to take care of the Visa and ended up with more trouble after that
Btw I left my passport at the Brazillian Consulate in Bogota so long they thought I was dead
I was just having too much fun in Colombia
