Bob,
My wife and I played We Ko Pa in the last week of Oct. last year, just as they were coming out of the overseeding shut down. The rate was good, but a lot of the ground game aproaches offered there were not viable with the furry rye grass. Still a compelling layout that is very easy to walk; I'd highly recommend it.
Carl,
Pretty much everybody has Bermuda and they overseed with annual rye; which makes it green. I'd prefer to play on the dormant Bermuda myself, the ball really screams across that surface; it's pretty hard to play run up shots off furry rye grass.
