My wife and I from near Boonville, Mo. Of course we haven't had a Mo geography class in at least 4 decades nor lived there, so where is the highest point in Mo?
If guessing I'd say way south down by Arkansas but I really have no clue except it ain't near our Mo River bottoms farm.
BTW I know I have seen that duck in the park ponds but haven't a clue about its type.
I took this pic here, where I live. It's the only one that we have seen. Other than the puff on it's head, it look like a Mallard, which are all over here.
