About to fly south for the winter (with cold feet)

We depart Thursday. Here is a calculation of my total travel time from Portland, OR to my destination (Reserva Añihue in far northern Patagonia):

AIRPLANE
Portland--Ft Lauderdale (8 hours)
Ft Lauderdale--Bogota (6 hours)
Bogota--Santiago (8 hours)

BUS
Santiago--Castro (16 hours, !?!!!)
Castro--Quellón (2 hours)

BOAT
Quellón--Raul Marín Balmaceda (12 hours)

CAR
Raul Marín Balmaceda--Reserva Añihue (40 minutes)

Total anticipated travel time: 53 hours. Yes. That is 2 days, 5 hours.

I'm not quite sure at this point why we decided to haul ass to Patagonia right away, but we did. At this point, I'm not quite sure of a lot of things. Like, how do I pack for three months' worth of traveling in one measly backpack? Is it true that you need a return ticket (proof of exit) in order to enter the country in the first place? Where the hell am I going? What if they enslave us at the Reserva and make us scrub the floors or something? How am I going to finish up my job interviews while I am in a place with no telephone? Why did I decide to leave the warm safety of my neighborhood coffee shop and depart for a cold, wet region much the same as my own cold, wet home state? I also remembered suddenly that my Spanish is terrible, more terrible than I like to make it out to be.

This is the usual pre-departure jitters. I know that as soon as I get on the plane, I'll suddenly feel resigned and calm about these crazy decisions. At least I have Aubstyle to suffer alongside me.
