Besides a game preserve, you don't have much for pheasants locally. I think the northern part of MO has phez but it's definitely not a destination state. Quail numbers aren't good either if anything like a couple hours south, but I would expect that bobwhite are the most plentiful locally for upland. You likely have more access to waterfowl than anything. Waterfowl is an expensive game to get set up for, but it's a lot of fun. In addition to waterfowl, you can hunt spring turkeys in MO. While numbers aren't what they were in the 90s, MO still has turkeys.
If you are up for traveling to neighboring states for upland, KS may be your closest options for pheasants and bobwhites. IL doesn't have enough pheasants to worry about.
