For those interested in the questions Roger sent our way - the answers are as follows: A bison's tongue is "blue" and it appears that the pronghorn antelope is not really related to any other animal that it looks like. Did you know that the female pronghorn actually has horns? We did see some bison in Yellowstone but unfortunately we could not sight any tongues so we were unable to confirm that the tongue is indeed blue. Thanks for the fun Roger.
