The park photographed is West Park, in Allentown. (I was born in and have lived most of my life in Allentown.) West Park was created in 1909, the first of nearly 2000 acres bequeathed to the city by General Harry C. Trexler. http://trexlertrust.org/ West Park was designed as an arboretum containing 78 varieties of trees and more than 300 varieties of shrubs. Allentown has 13.75 acres of park per 1000 residents.
