I can live with the OK and Not-OK sections as Mosca describes. I must admit I prefer non-smoking motel rooms and rental cars to avoid that stale odor when staying in one of those items that has been used by a smoker.
I am also very happy that smoking is banned on all public transportation, mainly(in my case) that means airline flights.
I happened to watch a rerun of The High and The Mighty (John Wayne Nite) and was surprised that almost everyone in the cast was smoking most of the time. It was also a look at the past to see a passenger plane on a flight between two major cities (HNL-SFO) to have only 20 passengers, 1 "Flight Attendant" and a flight crew of 4. (and two abreast seating in the whole plane)!! As I have noted above–Times have certainly changed.
