I took a picture of some tracks in the snow that I couldn't identify to show my brother recently.
(Okay really the tracks scared the holy-begeezus out of me: they were huge! After closer examination I did rule out Big Foot, Side-hill galaghers, and even Jack-a-lopes...the benefits of big brothers: many childhood fears!)
He advised me to next time put a dollar or something else beside to show perspective.
(Okay really I think they were just bunny tracks...the back paws overlapping the fore paws...but still scared the begeezus out of me at first...)
