Oscar Meyer Weiner Mobile Photobombed a Bison in Yellowstone It's not every day that I can write this phrase and be completely truthful. The Oscar Meyer Weiner Mobile just photobombed a bison in Yellowstone National Park. Yes, this really did just happen. Diana Borgmier shared this very unique moment just a few days ago on Facebook in the Yellowstone Up Close & Personal group. Her pic was then shared by Jimy Osburn. I would imagine that most of the drivers along with Diana in traffic had to do a double-take at what they were seeing. Jason Bradshaw added his pic of the Oscar Meyer Weiner Mobile in the Tetons.
