There was a DQ in Apple Valley Mn, which is just north of my location, that we used to go to a lot. I say was, because the place closed! Super busy place, so it wasn't that no one went there, but they just shut the place down. There were times that you could barely get in the parking lot, and other times that the line of cars went well outside of the lot. Just crazy busy. I have no idea what happened to it, but we're on a Blizzard withdrawal now.
