So, here's the scenario. I was playing in a tournament last month. I, for some reason, seemed to be compelled to hit my tee shots into water that day. Since the water was close to the teeing area, there really wasn't any relief to be had, other than re-teeing. On a couple of the holes, I hit my subsequent shots into the water. After finally finding dry land and laying 5, I happened upon unmarked drop zones on my way to my ball. They weren't marked anywhere on the card and there were no signs for them. Since I had already played my shots, I didn't use them and just took my medicine. However, in the future, are you permitted to play a provisional, until you are able to verify the existence of a drop zone on that hole?
