Whenever I drive to Vegas, I always make it a point to stop in at the Nike Factory Store. I usually pick up a couple pairs of shoes for the year.
Nothing too unusual about this location. Similar to any factory outlet store...tons of people and some items placed where they're not supposed to be. The staff during my last visit were pretty friendly and quite helpful.
Can't beat them for the products and the prices. The fact that sales tax is cheaper in Vegas vs LA is just another bonus. I'll be back, next trip to Vegas. Wait, that's in a month!
