Observations.

There are always a few things you do not think of before you travel. Things that shock you. There are two things that immediately come to mind, that shocked me about travelling down here.
1. The sun does not go down until at least 11 PM, maybe later. We were shocked when we were on a bus from Rio Gallegos to El Calafate that left at 8:40 PM. We were in the front seat of the bus, so we had a good view of the road and the countryside and a while into the trip, with the sun shining in on us, we checked the clock and found it was after 10 PM.
2. Its flat! When I think of Argentina, I think of the Andes, an amazingly large and treacherous mountain range. And yes, we are in the heart of that now, but on our way down south, and on our trips across the continent from Bariloche to Puerto Madryn and from Puerto Madryn down to Rio Gallegos and over to Calafate, it is nothing but flat land and shrubs.
