Wake up from your winter hibernation and thaw out on a hike with folks from the Group Against Smog & Pollution and Frick Environmental Center. With a view of one of our nearest major sources of air pollution, we’ll talk about regulations on such facilities, as well as how to protect yourself from air pollution while being active outdoors.
1-3 p.m., stepping off from the Frick Environmental Center (2005 Beechwood Blvd, 15213). Please register online. There's also a Facebook event.
