I agree. There's not much to landing a tailwheel airplane on grass. That's what they were designed for. Dealing with one on pavement is a different kettle of fish.
My tailwheel instructor suckered me on this. We went through all the pain and I finally solo'd on pavement. Right after that, he said that it was time for me to be "tested." This meant a flight to a nearby grass strip where there was a breakfast buffet near the field. He made it sound like a real challenge. I put it down there with no trouble and immediately knew that I had been had. That's what comes from having a helicopter cop as a flight instructor. This guy was also the helicopter pilot on the old Dallas TV show back in the seventies. He owned the helicopter that was used on the show.
Do your training on pavement and then grass will be no trouble whatsoever. Landing a taildragger on grass is really fun.
Makes me want to go find a grass strip tomorrow morning.
