Urban Hiking Lancaster City and Parks

For a change I decided to hike Lancaster city. Maybe hike isn't a good term for walking in the city. I decided to dub it "Urban Hiking". The park was really an afterthought, but I was driving by it, so why not ?:)
I am not native to this area but have lived here for a long time. I know some history of Lancaster, but I did not feel confident relaying what could have been inaccurate information.
