Walgreens turns out the lights for 'Earth Hour'


Deerfield, Ill. Walgreens plans to participate in "Earth Hour" by turning off its signs in Chicago and New York City for one hour starting locally at 8:30 p.m. on March 28.

Nearly 150 Walgreens stores throughout Chicago and neighboring communities will turn off all exterior signs, the company said. Lights in the parking lot, entrance and pharmacy drive-thru will remain on for security and safety reasons. Window signs in stores will inform customers of Walgreens participation and encourage community involvement.

In New York City, the Walgreens billboard in Times Square will also go dark.
