I have, a weather story, not really a storm story. Glider pilots really are the best (next to helicopter pilots ! I was flying a Cessna 340 out of South Tahoe. Was awoken early on a Sunday morning by the sounds of aircraft taking off. Usually I could not hear the airport but it was early and almost no background noise. I wondered why so many were leaving early on a spring Sunday morning. Checked weather and found an air mass was moving from east to west across the Sierras setting up wave and a rotor close to the South Lake airport. Decided it was time to load the dogs and wife and get an early start for home. Take off direction was east (toward the mountains). While listening to the radio, it was obvious many of these pilots should not be flying in the mountains, or even flying). I heard one "pilot" screaming on the radio his auto-pilot would not stay on because it was too rough. Many would take off and wanted to fly toward the mountains until they got to 1,000 ft before turning downwind (not a good idea if you are flying into rotor or the down part of the wave). As we are taught flying gliders, have a plan before you depart. I had planned to get as much speed as possible, suck the gear up as soon as I had a positive rate and as soon as the rate of climb started to diminish, turn down wind (at any altitude). Plan worked great. Usually in a 340 as soon as you leave the ground you turn on the yaw damper, it was so rough I made two attempts, could not get my finger on the toggle, so I went back to flying. My climb rate started to deminish when I had about 300 ft, turned downwind, over the lake I hit the up part of the wave, turned parallel to the mountains, climbed in the laminar air to 17,500 while thanking my glider instructors. Had a beautiful flight home, little rough on the take off and initial turn downwind, but really uneventful. I think, all power pilots should be required to take mountain flying classes and spin training. Nothing beats real world training! The other lesson Learned early in my flight training. I want to learn from the guy with grey hair, not a young guy. Experience, beats youth.
