On the ground, I checked the weather to find the clouds were now clear along my flight path, and there was a pirep indicating smooth air at 5,200 feet msl. With a full tank of fuel, I contacted ground, and after an inquiry from the tower as to whether I was sure I wanted to take off in this wind, I taxied to the runway. Cleared for takeoff, I took a deep breath and advanced the throttle. The airplane lifted off quickly, and I continued my climb until I reached 5,200 feet. As reported, the air turned to glass. I made my turn and continued my climb to 7,500 feet on my way to Lone Star Executive near Houston. The turbulence returned and bounced me along for the remainder of the leg.
