If you'll notice also, most of those rivalries are within the same conference and/or state. I'm with Biggin and The Beast, it will be big in NETN/SWVA. But, go just as far south as Chattanooga or go north to NOVA and you'll find almost nobody cares if VT/UT play each other.

Also, VT should be in the SEC before Mizzou. Mizzou has no business in the SEC. NONE.
