CityTrex aims to allow Savannah visitors the chance to "experience history in immersive and interactive iTours," according to Burton Sauls, cofounder of CityTrex. "Using iPods and handheld GPS units, visitors gain so much more than from being passive listeners."

Sauls said the system will allow users to "map out points of interest" and "customize a walking tour will create a richer visit." What's more, CityTrex claims the goal of making Savannah "a more pedestrian-friendly destination." That would be good for tourists and locals alike.

We couldn't agree more.
