We decided to go visit the U.S. Botanic Garden because a co-worker told us that the Corpse flower would be in bloom. It only blooms for 24-48 hours and has a smell of putrid, rotting flesh. It is HUGE. Unfortunately when we got there it was not blooming, but we did get to see a lot of the other beautiful plants.
Afterwards we stopped at the Natural History Museum to see the dinosaurs, fossils and other exciting things.
