Mike Piazza, Mark Blum and myself so far are playing. I'm sure we can play more than 4 to 6 people in a group if the course isn't busy. Otherwise, more groups!
I checked the cart situation and there are plenty of push carts. They have also posted a sign stating the rules of push carts on the course on tee boxes and greens.
NO DRINKING WATER ON THE COURSE! Bring your own small thermos!
