I like the location of the "old" Forest Fair Mall Cincinnati Mills (Metropolis, Bass Pro, Biggs).
I was in lust with the Ross/Tennessee Avenue location where the cinemas were, but it's going to be a complex for the Catholic Health Network or some such. As a central location still, the Gardens could be majorly revamped.
For MLS, I would think northern Cinci area anywhere from Butler County to Mason. Thoughts of the west side are interesting.
