It's just common
sense to only vape in smoking area's while in public,
vaping in public in non smoking area's only gives us a bad rap since most people are unaware of how e-cigs work, what the vapor contains and can think that they are real cigs. The perception is if it looks like smoke it must be smoke.
Being a fellow vapor I agree they should have been kicked out. I too was at a football game on Saturday and my lady's friend asked if she was going to vape while we were by the stands in a no smoking area and she said "I do not think it's appropriate". It's just common
sense.
