Smoking at the Pools

This morning I went to one of the lovely, clean, happy pools for a few laps and some relaxing reading in the sun.  After an enjoyable hour, two poker players who smoked drove me out with their smoke.

I know the pools are posted in "fine print" as NO SMOKING, but rather than I confrontation, I just went home.

Please post a more conspicuous sign, "This is a smoke free area" at each entrance and in the Pool Rules area.  

Thank you.
