Overheard a united pilot this morning telling ground control about an "un-identifiable" animal on the taxiway. The pilot, being a "CO native", called it an "overweight prairie dog" and ground asked if it was really a Sasquatch?... It was an interesting conversation over frequency. I was intrigued, so I headed that way. It was aN American Badger, and he looked a bit confused and pissed. I have never seen one of those, here, before and the last time I saw one must have been over 10 years ago.
