She went to a nature photography camp run by the Audubon Society.
It was a day camp, but she stayed overnight with Grammy, so she had extra fun there!
At the end of the camp, the kids each made a poster to show their favorite shots.
It turned out that Grammy doesn't have a color printer, so Leena printed her shots in black and white, then enhanced them with colored pencil.
She also invented a cute little character, "Rae," to introduce and explain her work.
Congratulations, Leena, on a job well done!
