'Curbside' shows exact location; things are right by the street, not somewhere nearby. Make sure to put the boxes on the curbside, so the cleanup crew can remove them.

Not Inside
'Curbside' signals something is outside, so you don't go looking indoors or within a property boundary. For donations, leave your bags at the curbside, not in the lobby.
Pro Tip 3/3
Government Services
'Curbside' is often used by local governments when talking about waste pickup or other services on the street. Curbside collection of recyclables occurs every Thursday.
