Takeoff description
space for 1 (max 2) gliders; some carpets covering the ground. Mostly cross wind from the left.
Pilot comments
house thermal on the left side of launch, behind 'brown' house. To reach Santiago, you need to get to 4000+m, very few ldg options >> see flight https://www.xcontest.org/world/en/flights/detail:cristobalorezzoli/4.12.2019/16:23
