I'm 30 and I had to look up "Main street". Those simply don't exist in western suburbs where I grew up (At least, not 90's+ suburb.). Let alone the boonies where there's simply 1 "super"market, one liquor store, and maybe one fast food restaurant.

I understand it, though. There very much was a main street downtown in my college town. It wasn't literally called "main street", however.
