5 miles. Meet at 9:30 am at the parking lot near the Visitor Center, 8601 Lindbergh Blvd. Philadelphia. John Heinz National Wildlife Refuge is the largest such refuge entirely within any city limits. We will hike about 5 miles in a loop from the Visitor’s Center, featuring the impoundment that affords views of the city skyline and lots of waterfowl. This is not a birdwatch hike but we will occasionally pause to watch the wildlife. This is a flat, level hike with generally good trail but some muddy sections are possible. RSVP: https://www.meetup.com/Batona-Hiking-Club/ Cost: $1.00. Leader: Gary Sawyer, muddyboots@comcast.net, 484-478-2607.
