No cross town rivalry can be compared it means something different to all who are involved. Being from the midlands, i care more about DF irmo, or SV RV than I do Stratford and Beaufort.
The best rivalries in the state are the ones that get every ones hearts pumping. I think by reading these message boards its clear that what Northwestern and Spring Valley is turning into might very possibly be the best Rivalry here. Its similar to the old RV vs. Irmo, and Chapin vs. BE.
