Harrah's has closed more casinos in Mississippi than they have opened.
But the proliferation of Casino Gaming in other states, more so than the economy, is the direct cause of this, not Harrah's egregious mismanagement. Tunica is just going to downsize. It is not going away.
The Coast gaming market has a little more resiliency, due to being more of a destination. Capital investment on peripheral amenities are actually on the increase. Although, if Florida ever opens up casino gaming (outside of its lucrative compact with the Seminole), then the Coast could suffer a similar fate (Downsizing/consolidation).
