The wind was on and good at Peña Negra when we arrived this morning, though waiting for it to improve was a big mistake as it slackened and went SE. Very frustrating as at this time the sky was looking very good to the West. A drive to Chia and some reasonable soaring had by all but with the thermal climbs too weak and low to commit to going over the back. A long Cb chain in the convergence some 20km to the N towards sunset.
