Today Glenn and I went to the Georgia Aquarium. That place is really cool! They have all sorts of creatures, broken down into 5 areas such as tropical, ocean, rivers, etc. Each section has some really cool life to see.
There's a lot I could say, but the photo gallery would do a much better job.
If you have the opportunity to go, you really should!
This image is taken in the 'Ocean Voyager' section. One of its main attractions is this tunnel which lets you walk (or stand on the moving sidewalk) and look up at tons of fish, including 2 whale sharks. The top of this image features a huge goliath grouper amongst the 100,000 other fish overhead.
