They come by plane, by bus, by 18 wheel cab painted green and gold.  Fans of the Green Bay Packers are everywhere in the Valley of the sun and they are ramped up for tomorrow's Wild Card game against the Arizona Cardinals.  I took a ride over to old town Scottsdale for lunch, and there they were.   Fans strolling about the shops and restaraunts.   I heard a guy singing around a corner and when I got there, it was a Gene Autry type, sitting atop a black horse.  Turns out, Gary Sprague, the singing cowboy and his horse Dusty are huge Packers fans.  His Saturday serenade is a regular gig but for the past 12 years, he entertained Packers fans at Max Mcgee's old bar in Cave Creek.   He says the place will be packed tomorrow.   You want packed, the Fox Sports Grille in Scottsdale was bursting at the seams an hour before the team held a pep rally at 5:30 PM.  A line of folks dying to get in stretched hundreds of people long.  Inside, team president Mark Murphy was there along with other Packer officials, radio color man Larry McCarren spoke as did ex players Jerry Kramer, Mike Flanagan and Robert Brooks.  Flanagan said it was "un-frickin'-believable" but then again, a winter game in a warm weather spot brings 'em down in droves.   They'll be in full throat tomorrow I'm sure.  Good thing it's a late kickoff so they can sleep off the fun they're having down here.  I'll have some last minute news Sunday morning and a complete review of the game tomorrow night. Ciao from Glendale for now.
