There's a BPS in Cincy, Fairfield Mall on the north side of town, don't know how much steelhead stuff they carry.
I'm not a steelheader but I don't think you'll find any opportunities in Indy or Cincy for them. Now if your staying in Cincy and just want to fish find a low damp on the Ohio River or the Great Miami River, bass, saugers and catfish a plenty.
