FALLS CITY -- When it comes to football rivalries, there are a lot of good ones out there. It doesn’t usually get any bigger than the Dallas Cowboys and Washington Redskins, or the Texas Longhorns and A&M Aggies. But here in Wilson County, there are a couple of rivalries that come close, and Poth versus Falls City is one of them. The two teams met again last Friday, and it was Poth that waltzed out of Beaver country with a 49-6 victory. . . .
