Heck, just noticed the thread title (sound of hand slapping forehead). Sorry for the dumb question.
But anyway, yes, welcome to PA.
If you don't mind driving an hour or two, it really does open a lot of fishing opportunities. Since you like small stream trout fishing, you'll need to spend some time in the Laurel Highlands (as others have pointed out). That area is loaded with small streams and many have wild trout.
Some things helpful to know:
PA has a problematic legacy from coal mining in past decades that has resulted in severe acid damage (Acid Mine Drainage, AMD) to many flowing waters so streams that appear at first glance to be "trouty" are sometimes barren. This is particulary true in the streams that are in western PA. If you see a stream with a distinct orange tint, this is probably one with AMD and not worth fishing. Many of us are a bit tight lipped about our favorite small streams, so do some exploring and get to know some of the forum members from western PA and you'll find some great small streams. Most of our small stream wild trout are brookies, but browns are common too and many streams have both. Wild rainbows are pretty rare in small streams. About 2/3rds of PA trout streams are wild population with no stocking. Most of our streams with wild trout produce mainly small fish with brookies averaging about 6" and browns maybe 8 or 9" - there are exceptions to this, but most of our wild trout are small.
The lists of streams on the state website known as "Approved Trout Waters" (ATWs) are streams that are stocked with trout. Just because a stream isn't listed as an ATW doesn't mean it doesn't have trout, it's just not stocked. Wild trout streams that have been documented to have high numbers of wild trout relative to the stream size are known here in PA as "Class A."
Small streams here in PA are different from what you're likely accustomed to out West: they tend to be covered in dense forest, often hemlock and white pine and can be thick with rhododendron making for a tough fishing experience but you'll get used to that quickly I'm willing to bet.
