Here's a day trip the Rath clan took in November to Squaw Creek National Wetland Reserve
http://www.squawcreek.org/
It's located in the North West corner of Missouri close to Nebraska. It's a wonderful place if you like water fowl--where in the winter it facilitates habitat for literally hundreds of thousands waterfowl migrants as well has Winter nesting for Bald Eagles. I learned about it in College as we went there on a field ornithological study. Amazing place to see if you are a bird watcher. I've been wanting Shawn to see the winter migration of Snow Geese, so we took a day to venture up there. It was quite a cold breezy day, so it was a short trip but worth the outdoors adventures with Patrick (the start of many more wildlife adventures for the little guy).
