The Ripley's (believe it or not) Aquarium is aparently the largest aquarium in the U.S. It was awesome. The tunnel is pretty neat.
We also loved Georgia while we were there. We ate at a restraunt that Bob really wanted to visit from his mission. It was a 3 hour drive to and from our hotel, but it was definately worth it. It was a buffet that they bring to your table. It was delicious!!
