I think that someday I’m going to travel to Madagascar with the primary intention of seeing (and, of course, photographing) the Boabab Trees.
With photos like this one or this one, how can you not want to hop on a plane right now and go?
You could also see some Lemurs, an African penguin (!), and even aardvarks.
While going to Madagascar would be cool, you could always just go to a zoo/aquarium, and an arboretum. 😛 It’s a little easier on the time-off, and wallet.
