MGM off-screen Due to system upgrades over the past week the Mirage line feeds to services like Don Best, SportsOptions and VegasInsider have been down. They are still working with both systems operational because the new system can not cash tickets written by the old system. Was told by sup at Mirage that cross property cashing is on the way but not players card use. While the switchover is taking place, expect line sources to be unreliable rendering the MGMs an off-screen out. The effort made to go check out what they have may pay off during this period.
