Clearly my reading comprehension is not great, ha.
I would say Castine is similar in quality. I think Castine is a bit shorter, but also a bit less rough around the edges than Wawenock.
It's a been a while since I played either one, as that trip was in 2004. Michael Moore might even be able to describe a few other Maine hidden gem 9-holers that I haven't seen like Wilson Lake, Grindstone Neck, Blue Hill, North Haven, Causeway, Great Chebeague, etc. Maine might not have many great layouts worth national recognition, but for charming little slices of heaven, it may be the #1 golf state in the US.
In Maine golf, it seems that the older, shorter, and the more boat rides you must take to reach a course leads to the best experiences.
