XY route 16, definately. The music, the leaves, the length and diversity of it. I just fly there sometimes to listen to the music and run through the leaf piles. The music is so dramatic, but so uplifting at the same time. I feel like I really am about to save the world, but I'm kind of melancholy about it.
I love it! I LOVE IT!!
