So i’ve been on a trip in Oregon for the past few days, and had the chance to see the Oregon Vortex (which is where a lot of inspiration for the design of the Mystery Shack came from). I had no clue that there would be anything Gravity Falls there, but there was a ton of Gravity Falls stuff in the gift shop (not actually being sold, just on top of a shelf over the cashier) and a display board right next to the entrance with Gravity Falls fanart in it. I quickly made a sketch to put in the display case, and while asking the employee to put it in, she said that Alex Hirsch had been there, and told a few facts about the inspiration for the show (that I already knew of course, but there was really no need to mention that :)). Overall, it was a great experience, definitely recommend!
