GTA IV: Back to the Future Mod

For all you video game nerds out there.  For everyone else, I apologize! But really, if you love the Back to the Future movies as much as I do, you might get a kick out of this too.

How did I not know this existed when I played GTA IV?  Why didn't any of you guys TELL me?  And you are supposed to be my friends...pssshhhh....

Anyway, here it is for your enjoyment.  I just may have to go back and play this.
