Pros:
it's Hawaii! The weather is always warm, and inviting.
The best thing about this course is the locals!
Great mix of shots, with lots of fun possibilities.
Cons:
No tee signs, tee pads, baskets, or even a correctly mapped layout. I completely understand though, and it is awesome that the group has put together a course even against the odds!
Other Thoughts:
Gen, David, Joe, and the rest of the HDGC were amazing. I posted on their forums, and immediately received several emails about playing with them. They really put the aloha spirit into playing the game!
Bottom line - if you are going to be on Oahu, and want to play disc golf, call Gen, don't hesitate. He will go out of his way to make sure you have a good time!
