Okay, it's winter and you're bored, so what do you do? You could build a trench and fly an X-wing down it in order to exploit an unprotected exhaust port. And actually, that's what filmmakers Mike P. Nelson and Aaron Dabelow did.
Right now, 49 out of 50 states are under a blanket of snow (Florida, get with the program), but that doesn't scares these Minnesotans, who typically endure winters that remind most people of Hoth. Out in the cold they went, to turn their winter wonderland into a Death Star run.
It's just like bullseyeing womp rats in Beggar's Canyon.
