Sorry I assumed you will be going to Buenos Aires. I was working down in Rio Grande, Tierra Del Fuego and the situation there is not good, I tried to Organise a PA32 at a flying club to fly down to Ushuaia which would have been a fantastic flight over the mountains, but they didn't seem to like my English Accent, but then the main street in Rio Grande has a memorial to the "Malivinas" war!
Any questions feel free to ask here or pm is fine!
