This is where common sense should come in to play. OB. That is not how the hole was inteded to be played. Don't use stretched technicality to get yourself out of a bad throw. It's about the integrity of the game.
This is stupid. The hole was not designed to play safe across that parking area. There is an OB line, that wraps around the basket on the rock wall and around logs. We can solve this by putting a simple line straight from center of parking area across 13's fairway. 13 is now an island (a really large one), and you cannot play 17 across the street. Done.
Or we can play 17 to hole 12's peninsula basket, as we will do tonght and the MAC, and this area across road will now be safe. No questions
