Almost every vehicle the city tows goes to one of a handful of lots. Here is what each is holding right now, and how long it tends to hold it.
Pins are geocoded from the address on the tow record.
Pound names here are the addresses the city writes on the tow record, so a lot that changes how it labels itself appears as a new entry. Phone numbers are the ones published with each tow.
