Google Maps Puzzle Fail

So, I'm not 100% sure why this is, but the George Washington National Forest boundaries (in green) seem a little off in this Google map:

I'm just guessing here, but I believe that the green wavy border should match up with the blue wavy line. So they'd look more like this:

It may not be Google's fault. I don't know where they get their National Forest boundary data. It may be a magnetic/true north issue, or an astronaut sneezed near a GPS satellite when they were collecting the data. Who knows. I'd just like it fixed. It's a eye sore, and obvious mistake. Come on Google...
