The Lenten fish fry is a popular tradition in many Catholic communities. In Pittsburgh and the towns around it, people looking for fish fries between Ash Wednesday and Easter have a very modern tool to find their fish fix — an interactive map. It's done by volunteer coders who want to foster community engagement, and it points the way to fish fries at churches, in fire halls and in restaurants. For western Pennsylvania, it represents a mashup of a tradition that many hold dear and the technological innovation that's helping to push the region forward. As the founder of the interactive map says, fish fries are an adventure.
