I saw that too. It sounds like a big problem waiting to erupt, for the die hard smokers aren't going to give up their habit. It will be like high school with smokers sneaking in their joints wherever possible.
They smoke on the ramps and far corners of the stadium now. Policy only means the ramps will be more crowded. IMHO Vaping is as gross as tobacco.
Maybe we can use the ramps for methadone as well. Get off my grass ....
