For smokers, finding a place to smoke at an airport can be a vexing proposition.

As more cities and states pass laws that prohibit smoking in public places, even airports that once had specially-designed smoking areas in restaurants and bars have been forced to tell smokers on long layovers to take it outside.

Not all airports are going smoke-free without a fight. Here’s a link to an article describing how the folks at Memphis InternationalAirport are challenging some of the provisions in Tennessee’s year-old Non-Smokers Protection Act.

In commemoration of the 40th anniversary of the death of Dr. Martin Luther King, Memphis International Airport is hosting an exhibit of photographs by renowned photojournalist Ernest C. Withers, who also photographed other notable individuals, including President John F. Kennedy, Mahalia Jackson, Supreme Court Justice Thurgood Marshall, President Richard Nixon, Elvis Presley, Isaac Hayes, and James Brown.

Through the end of April, travelers can view candid photographs by Withers documenting Dr. King’s last days in Memphis and the events following his assassination on April 4, 1968.

The photographs are displayed in Concourse B, just beyond the security checkpoint through the end of April.
