I am a retired biology professor and an amateur naturalist.
My home range range is the Darby Creek Valley, (Delaware County, PA, USA). I currently spend most of my nature study time while walking my dog in Pilgrim Park (Upper Darby Township) but we also do stints in Lawrence Park and Don Guanella Woods (Marple Township), Darby Creek Valley Park (Haverford Township), and Rolling Green Park (Springfield Township). From time to time I we visit more distant locations.
