Well, my flying school just got a few points reading this thread. I did a few touch and goes on grass as well as two or three takeoff's from the grass as part of my training.
The absolute best was doing a check out in Sweden to hire a c172. We flew up to a grass strip and over flew it. Noting the crosswind was totally across the strip and was about 15 knots he suggested this would be a good time to get used to Swedish conditions.
I was told that I could use half the strip only (eeek reduced to about 400 meters), first attempt a total screw up. second the same, third getting better. But, he insisted that he wanted to see one good touch and go before he would let me have the aircraft. Took eight attempts and he accepted the last one. My landing back at the grass strip we had taken off from was the best...but no cross wind there.
The guy was totally calm and relaxed during the entire event, gave me a short lecture on learning how to pronounce the Swedish VRP's better and handed me the keys to a top notch 172.
