If you were blind, couldyou navigate your way around a busy city street or distinguish betweena 1 bill and a 50 bill if you were trying to buy a beer at a bar?

These are some of the challenges visitors will face at a20,000-square-foot interactive exhibition coming to Atlantic Stationthis summer.

Premier Exhibitions, theAtlanta-based company that brought the "Bodies" and "Titanic" shows tothe city, is opening "Dialog in the Dark" in late August to givevisitors a sense of what it's like to be blind.

For one hour, you'll go through a market, take a boat ride, visit apark and get caught in the middle of a busy street scene with nothingmore than a guide and a cane.

To make the exhibit authentic, there won't be a sliver of light onthe tour. Cellphones, glow-in-the-dark watches and even kids shoes withsoles that light up will be prohibited.

The railing that visitors hold onto when they first enter willdisappear shortly after they begin walking. The only directionavailable will come from trained guides.

"What I like about this exhibition is you get in touch with sensesand your body and it helps you understand others," said Tom Zaller,executive vice president of Premier.

The exhibit, which runs Aug. 30 through March 1, is making its U.S. debut in Atlanta after a long European run, Zaller said.

Officials expect to attract about 200,000 visitors.

It's the latest attraction for Georgia's capital city, which isenjoying an influx of events that are bringing the city internationalattention. "Dialog" will join an exhibit this fall of terra cottawarriors and other artifacts from China at the High Museum of Art andthe King Tut show at the Michael C. Carlos Museum at Emory University.

"It's certainly going to launch during an exciting time for us,"Mark Vaughan, executive vice president, chief sales and marketingofficer for the Atlanta Convention and Visitors Bureau, said of the"Dialog."

"It gives our visitors another option and gives us more to go out and sell Atlanta as the place to be."

"Dialog" has been around since 1988, Zaller said, with more than 5million visitors from 20 countries. It has employed 5,000 blind workersas tour guides.

While its main goal is to demonstrate the challenges of the visuallyimpaired, the exhibit organizers also hope visitors will walk away withthe understanding that in the dark everyone is the same, Zaller said.

It's the same message used as a subtext of the "Bodies" show, he said.

"Atlanta is diverse culturally, but in the dark we are all the same," he said.

Visitors will go through five rooms with different themes. Most willbe surprised by the things they discover about their senses, Zallersaid, such as being able to identify leaves, a mailbox or an elevatorbutton.

For those worried that walking around in the dark could turn into anobstacle course much like what happens at home when the lights go out,not to worry.

"We won't put a coffee table or your child's Hot Wheels car in the middle of the floor to trip on," Zaller said.

Organizers will also be sensitive to people who might be overwhelmedby so much darkness. The guides will be able get them out quickly.

"It's not a haunted house," Zaller said. "We are not here to scare you."
