"Then there's the tricky part of posting these signs: The Allen County and Fort Wayne bans prohibit smoking closer than 20 feet to an entrance - a more restrictive ban than the state's which prohibits smoking within 8 feet of an entrance. That means that in Fort Wayne, signs must advertise the 20-foot smoking-ban range, while in New Haven, for example, governed only by the state ban, the signs have to include only the 8-foot ban."

Well, all that bit of melodrama merits is, "WELL, DUH!"

It isn't as if New Haven had any reason to be thinking they should trot out 20-foot warnings, and it isn't as if Allen County shouldn't already have HAD 20-foot warnings posted.
Kudos to Indiana, though, for not falling for the tobacco industry's preemption push. At least the state allows local governments to enact better protection than the state sees as necessary everywhere.
This particular article almost reads as if it were tobacco industry propaganda trying to get a preemption law into place.
