I love going to the botnic garden in the summer. I can spend the whole day there, it is peaceful, calming and very pretty. I haven't done it yet, but I would like to take a sketchbook there and just draw all the great scenery, maybe next summer I will do just that.
One of the neatest things about the Atlanta Aquarium is that you can literally walk underneath the glass and look up to see the fish swimming above you, including this gigantic WHALE SHARK!
