Dusk 2 Dawn

 is an abandoned convenience store in Gravity Falls, Oregon, the property of Ma and Pa before they died (it was closed down soon afterwards). It was first seen in "The Inconveniencing." There were also rumors that a "double murder" took place there.

History
Dipper and Mabel Pines visit this convenience store with Wendy and her friends Robbie, Lee, Tambry, Nate, and Thompson to see what lurks inside the store and indulge in teenage mischief. It turns out that it is haunted by two ghosts named Ma and Pa Duskerton, who owned the store until they were struck down by double heart attacks after hearing "disrespectful music" played by a group of teenagers that were banned from entering the store. They tell Dipper that they haunt this store because they hate teenagers. At the end of "The Inconveniencing," the lights in the store flicker off, suggesting that Ma and Pa are still haunting the store.

Trivia

 * Oddly, even though years had passed before the events of "The Inconveniencing" and the ice freezer wasn't on, when it was in "The Inconveniencing," the ice was perfectly frozen.
