OK, now i have a good point to start...
I made some time ago a big picture of Las Vegas, using many google maps ( don't tell 'em) stick together (i mean a digital version, not a paper and scissors work).
I'm typing the names of casinos open in black (when they miss, there's almost everyone of the biggers) and the closed in red.
I'll accept every kind of help, i'll post a beta version of the map soon, and any comment or info will be much appreciated.

Bye
