Yep, if ya pinch one out here real hard, then you can leave scorch marks on the green! You will also leave score lines on the bottom of your irons.

Well I was down to my last few golf balls and it was a Rock Flite that I managed to spin off the green!!
But I do agree with practising/hitting shots out of the beach/bunkers as it teaches you so much without actually getting bogged down in mechanics.
A certain Spanish Wizard called Ballersteros learned to play golf this way and he did ok didn't he?
