I was ice fishing and had a muskrat bring weeds up through my hole in the ice and sit there and eat it right next to me. I remained motionless for several minutes. Pretty funny that it didn't realize I was a human. Finally, I moved, it looked up at me, uh-oh! Jumped in the hole and was gone.
I've had them come up in holes near me a few times, but that one was right there by my boots. Pretty neat moment.
I spent my youth chasing muskrats with my rowboadt and/or skindiving, so they have a special place in my memories.
