Light winds and a low inversion layer, not as hot as it’s been. It all added up to small thermals bumping against the inversion layer 500 feet above the peak. Had to bank hard and push out to stay in the little rodeo cores. Got 500 feet below launch once, briefly. Test flying a Wills Wing Falcon 4 170. Nobody else was flying so I didn’t want to land in the valley and try to cadge for a ride up to get my truck. Thus I didn’t venture very far from the peak.
