I live in OH, and I have family in PA, and honestly, the weather is very similar in both states. They both have 4 beautiful seasons and the gardening is great. I am not aware of the PA housing prices, but in OH they are low if you are a little bit away from the bigger cities. You can still buy land for a good price in the rural areas, which I assume is where you are looking. Ohio is FLAT. Unless you live in Southern Ohio there is no diversity in the landform.
Raw milk is illegal here, I guess PA one-ups us there!
