Check out this enormous leaf I picked up at my Mom's.
The one on the far right is one that I got from the park the other day, thinking that it was pretty big. Ha! The leaf on the left totally pwns the leaf on the right :)
(excuse my man-hands)
I measured and its height (not counting the stem) was 13.5 inches. Its width at the widest spot was 18.5. Yes, I took the time to measure a leaf. Occassionally, nature deserves a geek out :)
