Went this afternoon and played all 18.
I can agree, you should probably wait until the rest of the grass has been mowed the rest of the way. Not so much because of how tall it still is overall, but more because of the big piles of fresh cut prairie "grass" that are everywhere. Myself and all the others seemed to be spending an excessive amount of time searching for discs (which were carefully watched) within a 10' area because they were buried in the "hay". Many of the tee pads also still have very tall stuff growing up around and onto them.
I suggest, even if they get it all mowed on Monday, wearing long pants or heavy, tall socks and some rugged shoes. I am sure they won't be bagging the clippings when they mow and you can still expect to be deep in piles of them, picking up burrs, cling-ons and other miscellaneous pokey things.
All that said, I want to give a big thanks to Mark Dude, Greg Doh and anyone else that helped get the baskets installed in such a timely fashion. "Thank You!"
