There are two things I like about the Atlanta airport. 1. Their trash cans have built in compactors, so there is less emptying of the cans and a lower volume is sent to the landfill. 2. They have the highspeed hand driers in the bathrooms that I first saw at SFO. These are more energy efficient, and dry your hands crazy fast, nothing like the old style hot air driers. I wish all airports had these things.
