Of course I am not endorsing smoking (that is quite taboo these days, I'm sure!) but over here in this part of the world you can see "SMOKING AREA" signs (or "yes smoking" signs if you will) around to designate smoking areas. It's like the NO SMOKING sign but with a green circle and no crossed line. So That's what I'm providing here, for anyone who needs it!
