Trump won big in rural parts no surprise. Harrisburg voted so heavily Democrat as it is 52% African-American, 18% Hispanic while whites only 30% and a lot living there would be civil servants so naturally lean Democratic unlike surrounding areas which are quite socially conservative. Biden also one most adjacent boroughs by sizeable margins although not quite as lopsided as Harrisburg but again large minority although not minority-majority and lots of Civil servants. Eastern part near Hershey in Derry Township went for Biden too and I believe Hershey is very much white working class so an area you would think Trump would do well in. Famous for chocolates. Northern part is more hilly and very rural so went for Trump in landslide.
Lots of Harrisburg suburbs are in Cumberland county and it was unlike Dauphin county suburbs, pretty evenly split (but those ones a lot whiter) while rural parts pushed county towards Trump.
I have been to Hershey park many times as I am from Northern Virginia including on my high school end of the year trip.
