Field Notes
I’m happy because I got to work with friends. We also found the plant fast. Also this project was fun! I see tall trees. I hear construction and wind against leaves. I smell sweet good smelling smells. I am surprised I found good smelling berries. I was surprised it wasn't hard to find, or short. Some problems were... We had trouble finding the GPS calculations. We also tried to smell the bark, but it has no smell.
