Hello all, I'm looking for the name of a 1980s horror/zombie flick, it's general plot is of two brothers that get forced off the road by a bunch of rednecks, so they go into the nearest town to get help and gas and soon realize strange things happening. Basically there is something in the water supply that is causing everyone to turn into zombies/creatures and it's left up to the strangers in town to save the day. Any help would be greatly appreciated.
