One of the easiest and safest ways to get outside while staying at a safe social distance is to visit one of our parks here in PA.
This https://www.dcnr.pa.gov/FacilitiesMap/Pages/default.aspx" target="_blank">interactive app from PA GOV shows you exactly which parks are open, by which county, and what they are open for.
Happy hiking! And, remember to follow all of the best practices!
