flying technique(s)

this quote appears in Aprils 2006 Soaring Magazine 1-26 Championships Article by Kevin Ford. " I used a technique that Irn Jousma taught me long ago for flying on cloudless days: when in sink, fly across the wind, and when reaching lift or reduced sink, turn into the wind. The theory is that the lift and sink are organized roughly in streets aligned with the wind, the same as on cloud days." Maybe a tip for the transistion from Highway 5 past Nenanche in the Antelope Valley.
