NOGALES, Ariz. (AP) - Authorities are hanging color-coded flags at a Nogales park in a bid to inform people about the city's air quality.
City officials say the flags were hung to help people make informed decisions about outdoor activities.
The flags will signify how clean or polluted the air is.
For instance, a green flag would show that the air is safe, while a red flag signifies that the air is unhealthy.
The city began hanging the flags in Fleischer Park this week.
