Just for another perspective, we were there in late June, and we did grab a boatyball at Cooper. It was a pretty easy process, though maybe I was just lucky to get one that day. Either way, I was glad I did, as the field was full by early afternoon.

We didn't bother with bb for any of our other stops, and didn't have any trouble finding balls, though we tended to arrive pretty early in the day and were obviously in the low season.

Not trying to step on toes or discount some folks' strong feelings about this, but just adding an average joe's opinion, that it worked fine for me.
