Ridge soaring at METU

3 different sites within a 20 minute walk (fast pace!) are soarable in the METU grounds behind our apartment - two Northerlies and a NE. This is the original N site below. I'm pretty sure that the thermic air is too rough for safe flying after the last two experiences. The air is too turbulent. Walking to these sites on a regular basis with a 20kg glider is a good way to get fit. I lost 2kg doing it.
