Hey Kevin welcome aboard-- you have lot of great fishing there in the the Missouri trout parks and in streams like the Meramac-- (whenever i was traveling through St Louis, I always used to take some extra time to fish the area around cardiac hill, and it was always a treat). And since you've been a very successful bass fisherman you can put a lot of that to good use too when you start terrorizing those same largemouth and smallmouth with a fly rod.
You're also blessed with some great fly shops--- In addition to Feather-Craft Feather-Craft Fly Fishing | Fly Fishing Rods, Reels, Waders, Flies, Fly Tying Materials | Sage Rods | Simms Waders | Since 1955
there's also T. Hargrove THargroveInc
Both are excellent shops with great folks.
Although working the 2nd shift might make it difficult to make a lot of meetings, you might want to consider looking into a local fly fishing group-- like a local Trout Unlimited chapter or a FF club affiliated with e Federation of Fly Fishers. Most will have casting clinics, informative meetings tying classes and group trips to local waters. It's a great way to speed up the learning process.
