Hey all, i have started up a group on yahoo.If you would like to join please feel free to do so.the more people that sign up the higher it gets on their listing. Peace Bob http://health.groups.yahoo.com/group/Bobsglass/ By the way, someone made a post about glass color changers and it they would change it you smoked more then your tobacco out of them.One thing i would like to point out about that is,if you share your bowl do the people you share with want to be smoking everything you have smoked out of if before hand.Just something to think about.
