Of course we're talking about the FBR Open (sorry Lee), dubbed "The Greatest Show on Grass," it's also the best-attended PGA Tour event of the year. And it opens today in Scottsdale, Arizona where spectators can pick up free XM radios for use each day through the weekend.
 
Pulling in over 500,000 spectators, the annual FBR Open takes place at TPC Scottsdale today through Sunday (though the on-site partying actually began on Monday). Phil Mickelson, Vijay Singh and Chris DiMarco are among the golfers set to compete.
 
XM is carrying the tournament live on the PGA Tour Network (ch 146). Each morning, XM is offering 1,000 radios for spectators to use throughout the day, and fans can also opt to buy XM receivers on site. This marketing effort at PGA Tour events is known as the "Fan Enhancement Program," and it’s the first one of 2007.
 
If you are one of the half-million people who happen to partake in the enjoyment, look for the very lovely (and talented) XM product "specialists" stationed at the XM booths, one located west of the Hayden Road bridge and another adjacent to the practice putting green.
