Columbus has a couple of stores that *also* have trad gear, but mostly it's compound stuff as econnell71 says. Right along I-70, we have two Gander Mountain stores (one east of town and one west) and about 25 miles north of that (close to Delaware) there is a great shop with better trad stuff.
Holler if you need addresses for any of the above.
