assuming you're located...
roghly mid-way between Tunica and Biloxi, at least you have an Interstate to travel either NW or South for better games. Vicksburg is mediocre and the few casinos there watch the action like a dog on a bone...but you already knew that.
My only good memory of Philadelphia was seeing Dr. Hook at the Choctaw Indian Fair, long before casinos came. I used to be an Air Traffic Controller (civilian) at Meridian Naval Air Station. You cannot believe how happy I was to leave that dismal place!
Forgot to add that the Philly casinos also drag in the flyboys from Columbus Air Force Base as well. Birmingham must drag in tons of slot players via bus.
