      Like surfing a giant invisible wave.  Have to find the best lift by a combination of pure seat of the pants stick and rudder and listening to the howl of the variometer.  Sometimes you will hit the center of lift and it is like pushing the UP button on an express elevator in a skyscraper.  You know the kind, where you actually feel the Gs of vertical acceleration.

        I was in a gaggle of three near Pagosa Springs, CO once, and all of us had our varios pegged (>> 10 knots up). One of us had an averager and it claimed 29.9 knots over > 5,000' of vertical. We don't know if it was pegged too, or that was our actual speed. There wasn't a wave window there, so we had to bail on the lift before 18,000'. :-(

        I've also had to run away from developing cu-nims that were probably more like 40-50MPH up.
