Some holes are now hole in one possible, such as Treasure Cove hole 4, Altitude hole 2, Altitude hole 6, etc. They don’t have achievements. They should have achievements, didn’t know where to put this, as it was probably just a mistake.
I think that a lot of them don’t have achievements, because some are just insane to accomplish. You can get a HIO on hole 9 of TC, but that isn’t an achievement either. But then again, Hole 15 of Garden is a HIO achievement, which probably stumped many players. I think the HIO achievement line should be drawn at levels that were designed for a possible HIO.
