This is tough! I love Pennsylvania... but I love the state of Washington! I was born and raised in PA, but I love the rainy weather and grunge music from the Seattle area.
It's really hard to pick between them... but I'm going with...
Virginia for me because it's the right temperature, there are moutains, and my father lives there. In fact i'm there right now! (I visit durring the summer, winter, and spring break.)
That's what Kentucky is like, when I went to Oklahoma, it was hot, flat, etc., here in Kentucky, the temperature is just about right, and it has mountains.
