Hey, Go Pennsylvania! I spent a great chunk of my life there in York, my hometown. If you enjoy the country so much, you should pay a visit to Pinchot State Park. It's a great place to be! My father stays there all the time. It's got a massive colony of trails, even a museum! Take a visit with your son, looks like he'd enjoy it as well!
PS: I'd love to get my hands on one of those tractors for our land over here! =D
