Saturday at the springs

Hi! Just came back from the springs. There were about 30 people today.
Mid day a truck load of asian guys and gals came in. All were textile. All were so noisy that they managed to destroy all the calmness and tranquility the springs offer. Their kids were screaming, jumping, and splashing in the pools. I could not relax, so I packed my staff and took off. I saw a dog in the pool again. I do not want to bring back the infamous dog-in-pools discussion again,but would anybody object if I order and install a sign that say smth like, "No dogs allowed in this pool" or "This pool is dog free"? I am open to your suggestions. I guess some people want to bath with their mots, so let's compromise. Let's have one( I am not asking for more than one) pool that's dog free.
