I remember that grant to UD, and that was before RWJF took over MADD, but was already well on it's' way to destroying nightlife (bars/clubs) in Delaware with all the grant money it doled out to push the smoking ban.
As to the drinking age - I agree with you. The drinking age was 18 when I turned 18 in NY, and I was already on my own in my 20s in Delaware before NY went to 21. Delaware was already there.
Personally, I am torn on the smoking issue. I really don't like the smell of cigarettes (but I don't mind cigars or pipe smoke), and even before I turned 21, I didn't like the smell in my hair and on my clothes after coming back from a concert or whatever. The DE smoking ban passed shortly after I turned 21, so I got to enjoy the smoke-free environment. On the other hand, I think such legislation is an infringement on private property rights (people don't have to go to restaurants and bars).
