Atlanta
I loved the Botanical Gardens in Atlanta. I went with my grandma, uncle, and cousin, and it was just fantastic.
There was a whole section in the greenhouse devoted to orchids of all varieties. There were also birds flying around, completely fearless, and would walk right up next to you. (click to enlarge pictures).
There was this train exhibit called “Locomotion in the Garden” that was like a little world with a bunch of different trains and buildings and tracks made from branches. There was a waterfall, and a little island. Amazing.
Sorry, the quality of these isn’t great.
