starting in buenos aires and probably flying back to toronto from lima in peru (although i havent bought my ticket yet) the itinary is still open as i have no plans, but probably go through la paz and titicaca as well as machu pichu. but before heading that way, i want to go somewhere in brazil (round trip from BA by bus) still not sure where in brazil but not anywhere far in (probably close to the border) i need some advice: -which vaccines should i get? -is the brazil detour a good idea? or should i start there instead? -i have a 80 litre pack... is it too big? -should i bring a sleeping bag? also, is there a trvel-time map of south america so as to give me an idea as to how long it will take to get from one city to the next? thanx!!!
