When I first saw him he was in a stall and the wing surged so hard that he went slack and fell thru his lines. His arms and legs where flailing and he went in to a series of spirals, spins, etc. He was stuck in a downward spiral and I looked at Kevin and we both thought and had time to verbalize he was going to have to huck his reserve.. At the end of the day he lost approx. 1000 vertical feet and recovered. We waited for another 15-20 minutes and set up to launch at about 4:15. Kevin was sporting a Trango 3 and left on a good cycle and immediately was above launch and pushing out front going up. I launched after another local pilot got airborne and was off the ground as soon as I turned and started to push forward. The wind was SW at approx 10knots. There where really sweet and what seemed to me to be fairly organized thermals. I worked to actually fly on purpose and not just boat around aimlessly. it was interesting to set up a course to follow. Anyhow, the boyant air made it easy. Had fun for a couple of hours and headed out. I would do it again. It beets working
