Took off Just before Granger but did not find a strong enough thermal to stay up. Its definatly all about the timing. I waited to make the turn to take off until I felt the wing try and lift me off the ground. Thought I had hit it perfect but the thermal diddnt last. Got a few small bumps on the way to the LZ but nothing sustained. Every flight is a learing experience. Take note of all the indicators during your flight to learn and improve.
