I remember these chips growing up in central PA. They came in a white and blue bag, little greasy but very crunchy and delicious. My parents would buy either Gibbles, Utz, Martin's or Groff's chips, whichever was on sale. All are very good. The other 3 are still available, but sadly I do not think Groff's still exist. As best as I can tell, from yahoo searches, the owner of Groff's Snack Foods was Horace Groff out of Bowmansville, PA. He had several business partnerships including a very successful potato chip venture in TX called Groff's of Texas. Unfortunately, his other partnerships were not as succcessful. Apparently he had borrowed lots of money from banks to finance his other businesses using his company as collateral. I'm speculating, but he probably got in over his head and lost the company in the mid 90s. In addition, it appears he had lots of tax troubles in the mid to late 90s. The trail goes cold from there. What a shame.

I live in Canada but I use to travel to Cherry Hill New Jersey as I worked for a Drywall manufacturer that had a plant in Camden New Jersey. As I got to know some of the employees one guy was eating Groff's Potatoe Chips. They were the best. I liked them so much I tried importing them to Canada and sell them to the larger supermarket chains. But in the end with the weak Canadian Dollar(Back then not now) and the 8% Duty on chips it wasnt worth it. A bag of Groffs would have retailed for $3 dollars back then and that was too expensive. My favourite was the Jalepeno and Cheddar and the Green Onion.
