The original Gibson's were smaller stores in rural 3K to 6K size towns. They had a nice niche with little competition in this market. Wal-mart started to infringe into the smaller town market. The response was to counter with larger stores in larger markets along with the name change to Pamida. Pamida was chosen in reference to co-founder's sons Pat-Mike-David.Ah yes, Gibson's became Pamida -- I saw refs to Pamida earlier the thread and I didn't make the connection.
My closest connection to Pamida was that I once had a concert date with the other co-founder's step-daughter. It was the most thorough background check I ever had when picking up a date. She was brought home on time.
