Mostly about population density and geography.... Largest portion of the population lives East of the Mississippi.... One of the largest vendor Displays at WingDing is WingStuff based here on the West Coast.:wrong: Geesh, for all of us in the West, that sucks! 5 years then since it was west of NM (Billings, Montana in '07) What a bummer! I guess it's all about the vendors. Oh well . . . maybe in 2013!
