Thanks. That I experienced that in Condor and saw that on a Youtube video where the wave at higher altitudes were ridden. There I understand one is far from the ridge. And you have to find it. It invisible. But lower down I feel you have to fly too far from the hillside. Almost like a tunnel of no lift under the updraft.
Also fell off on the wrong side of the rigde and couldn’t return in Condor. Frightening.
Btw. Like your avatar. Very funny.
