The New Smoking Section?

What is going on at our local park's playground? It seems to have become the new smoking section. Maybe it's me being a really annoyed mom wanting my children to be able to breath fresh air. Maybe I don't want to have to worry about them stepping on partially lit cigarette butts. Just wondering if this happens at all playgrounds or if it is just ours? I get it, smokers are being banned from all sorts of public places and are pretty much limited to outdoors only. Where are these smoking parents suppose to smoke when they take their kids to the playground?
