Nice read Fuzz.
Sounds like youre in a nice spot there.
Can understand why they don't have lights. Playing on grass day and night isnt great for the longetivity of the courts which are already high maintenance too.
We have State Grasscourt Championships at my tennis club just after Christmas. I will take some video and report back. Im guessing because its very dry here over summer there isnt much moisture under the surface here. The ball sits up beautifully in the hitting zone.
