The last time I was at a Walmart was around Xmas when I was looking for a small appliance that my wife wanted. This was at the location on the west side of Green Bay which is on the Res. When I came out of the store, frustrated from all of the people and the fact that they didn't have what I was looking for, I heard pow wow music blasting from a car. There was a Native American driving around the parking lot with all 4 windows down with the volume at what must have been near max. There was a guy walking behind me and he said, "sounds like he's rockin' out to Sitting Bull's greatest hits!" I think I was still laughing as I was leaving the parking lot in my truck.
