I grew up in Philadelphia. I often could tell what part of the city you lived in the same way. When we moved to CT, people knew we were outsiders.
Amazing how many people in recent years never traveled more than a few miles from home.
Been about 20 years, but a neighbor wanted to get an appliance his wife asked about. Local store did not have it but I found a store 30 miles north of us in Worcester MA had it. I suggested he buy it there. His reply? "OK, I'll go but you'll have to drive"
