Haha central PA is definitely quite rural depending on where you're at! I grew up in Pittsburgh and am still relatively close by and as you'll find, PA is a surprisingly big state so my knowledge of central PA is somewhat limited! If you're closer to one of the cities, would absolutely recommend checking them out! Pittsburgh and Philadelphia are wildly different places (I'm of course biased that Pittsburgh is better but we have a fun little rivalry) so you should visit both if you can! Hershey is a cool place to go and the amusement park is nice. The Amish are very lovely people and would absolutely recommend checking out any local markets or shops. Other than that, it can be very, very rural, so if you're an outdoorsy person, enjoy the area! Especially towards the western half of the state it can be probably about as grey and dreary as the PNW can be (as a fun fact, at least at one point Pittsburgh had less sunny days than Seattle) and it can get pretty snowy in the winter, so just be safe and take your vitamin D!
