There really is not a Malvern PA. Its a suburb of Philadelphia, as Kanata is to Ottawa. Essentially, NYC to Washington DC is one city, with the occasional one-acre field breaking it up. This includes Philly and the suburbs.
The big claim to fame here is the Valley Forge Historical area, which is a field with a museum and a half dozen artefacts that “George Washington may have been in the same area of, maybe, but we don’t know…” Fortunately, the museum is free. If I had paid for it, I’d be pissed big time.
Oh, by the way, the world HQ for the QVC shopping network is down the road. You can tour that too! I won’t. Its a nice enough area, but like any suburb of a major metropolis, it looks to the center city for its justification. Looking to Philly for justification? Hmmm…
