Viral marketing campaign for a new video editing suite, most likely.

HOWEVER...

For the sake of argument, if I ever woke up 6 years in the future and couldn't find evidence of another person anywhere, my first thoughts would be:

1) Head to GLP, they'll know what's up. If not, post an AMA thread.
2) I am going to "test drive" the SHIT out of a Dodge Hellcat as soon as I find one...
3) Guns and ammo are all 100% off right now - perfect time to stock up.
4) Wait...there's not even any BODIES lying around. Whatever caused this is a VERY efficient predator, and if it's a very efficient predator, chances are good that it knows I'm still here...meaning there's a good chance I'm being stalked right now.

Okay, items 1-3 are gonna have to wait...let's get indoors, find a good lookout spot, and just watch for a few days.
