The Fairfax County Park Authority is encouraging participation in the first annual One Dark Hour event.
On April 22, the Fairfax County Park Authority is hoping residents will join them in turning off their lights to raise awareness of the importance of dark skies. Park Authorities ask you take part by turning off your outdoor lights between 9 and 10 p.m. on Friday, April 22, and encourage your neighbors to do the same.
