I don’t know about the largest potato. But I’ve seen the largest potato crisp in the world. And the largest potato masher collection as well. All in Blackfoot, Idaho at the Potato Museum. Exciting.
Blackfoot: that’s big tater country. I used to load Idaho Spuds——for JR Simplot the tater tot guy-—into Idaho Spud bags-—in Oregon. I was in high school and that was probly my first contact with big time, lying thru the teeth, advertising.
