Yeah, but you have to do this:
For a couple months a year, regardless of the level of rain. Lots of low lying areas there, though they do the best job they can keeping it playable.
I am not advocating that RR should be below a 5 for this - I absolutely think it's a 5 - just pointing out the inconsistency in saying that soupy fairways for a couple months = <5, but RR is a "permanent 5".
My issue isn't with "a couple months" -- my issue is with holding water to the extreme both inside and outside the spring months, something I have heard repeatedly about Harmony Bends. I expect to play in wet conditions in spring. I don't expect to play in ankle to calf deep water the day after it rains. In my mind, that level of water retention is a significant detraction from a "best of the best" experience.
Also, my use of "permanent" refers to the fact that it's a permanent course -- my favorite course of all time is the Kensington Toboggan temp course.
