Accompanied by a few 14-year old girls, I arrived at the Cape Cod Potato Chip Factory at 3 p.m. on a Friday afternoon in June and followed the signs.

Once inside, we said hi to the women at the reception desk and walked down a narrow hallway, reading the signs and peering through windows.

We saw potatoes falling through a chute and on conveyer belts. We watched as workers grabbed random samples of potatoes potato chips and more potato chips, but we weren’t allowed to take any photos. We learned that it takes a lot of potatoes (4 pounds) to make only 1 pound of potato chips, and we observed the chips being weighed and packaged.

At the gift shop, we were given free samples (sea salt and vinegar and sweet mesquite barbeque) and bought two bags for lunch the next day (feta and rosemary and 40% less fat).

Located at 100 Breed’s Hill Road in Hyannis, Mass., the factory is open for free self-guided tours Monday through Friday, 9 a.m. – 5 p.m.
