Greg,

The only Seminole casino I have been to is at 377 and I40. It is at the 200 mile marker, exit 200, on the south side of I40.

There is also a casino 1/2 mile west of 177. It is about 4 to 7 miles South of I40, turn East at the flashing lights. On your map I would guess it to be about 1/2 way between I40 and 270. They do not have tables at that location. I don't believe it is Seminole.
