Not many birds from Waubay East. The further West you go from Waubay, the better. Lots of WIA land to hunt, but much if it is so large that you just can't cover it. Look for small grass/weed/sloughs near corn and hunt them. Get West at least as far as Bristol, hunt North and South from there.
Plenty of birds, and lots of work to find them. Lots of fun too.
