Yep! I LOVE this show, Gravity Falls. It's so good! I live literally right near where it's supposedly placed. So cool! They sure got the landscape right, lots of pine trees XD XD. Anyway, I highly suggest it. My whole family watches it together! No spoilers, I'm working my way through the second season at the moment!
