All the major online books plan to open for business in Arizona on September 9th. I was trying to find the shortest distance from Las Vegas to Arizona where you could drive over to make your bets and drive back to Las Vegas in a roundtrip in little over an hour. The best place I can see is the Kingman Watch or Hoover Dam Lookout. The problem is would you be able to pick up Arizona cell phone service or would your phone latch onto Nevada service being that close. There is no way to know unless you go out there after 9/9. I know people run into problems in NJ near NYC. If you are in Hoboken and walking along the river the location service could still have you in New York State in which case it wouldn't work. They all use GeoGuard software and technically it's suppose to pinpoint your location within 50 feet just like GPS. If it works and you live in Las Vegas you would now have a ton of outs and also be able to bet on boosts and promos. I don't even know if they have cell towers off 93. There are no services to Kingman, AZ so this could all be a moot point.
