On Jan-19 I rode 100 km from Punta Delgado to Rio Gallegos, generally N - NE direction. In the beginning the wind was from the N, so pretty strong headwind. Later the wind shifted to W, and the road at the end had some stretches more to the NE, so there was a tailwind component to it. When I reached this sign I was actually enjoying a few rare sections with good tailwind.
