A foursome at Timpanogos.
We were the last tee time and the group had no one ahead of them. They had carts, we walk. After hole 14, I think we were right next to the tee for hole 5. With no one on the front 9 so we just did holes 5-9 (5 holes) while they played holes 15-18 (4 holes).
At the end, we were getting in our cars at the same time even though we played an extra hole. Playing behind them was so frustrating.
