We had a Moose in our pond summer of 2008. It walked around the edge of the pond, entered, ate all the lily pads, hung out for about 20 minutes then swam away. It got to the other side of the pond, got out, walked into the woods and we haven't seen her since. This was probably a medium sized, young moose, maybe 700 lbs.
I'm posting now because a friend and I were talking about it and I remembered I wanted to show you all this fun happening.
