Why wait for 30 days of comments when one week shows that out of 800+ responses maybe 5 ppl want them to remain???  It should be personal choice and should have ended about a yr ago.  I predict that years from now there will be studies done on young adults who are having health problems due to years of breathing in the same thing that environmentalists claim are "killing the world".........carbon dioxide.  Who knows what this is doing to developing brains.  And I hope, IF this was ever to be put upon us again, everyone puts their foot down and just say H E double hockey sticks "NO"........if everyone just said no then that would be that.
