I live in Cincinnati, which is a heavily Catholic town. So every Lent the Greater Cincinnati area has dozens of weekly Friday Fish Frys. Everywhere. Its a sort of unorganized festival of fat and fish.
There are people who make it a sort of pilgrimage to go to a different a Fish Fry each friday with a group of people.
All the restaurants will have fish.
Some Churches even have DRIVE THRU Fish Frys.
Does your city do anything like this?
