...some of the casino close due to:

1) poor managment

2) large debt incurred in building or remodeling

3) casino was aborbed by another gaming company and closed because
of future plans for that real estate

There has to be other reasons why they close....since they have the
advantage when it comes to gambling....pay out to winners must be
a small liability...or all casinos would remain open forever..

Just my thoughts on the matter...
