The zombies are attracted to sound, right? Just get an abandoned car, drive it out into an open field outside the prison, crank the wheel all the way, stick the horn so it stays on, and jam it in reverse and jump out. The speed of the car going backwards in circles will plow through hundreds of zombies before it runs out of gasoline.
Rinse and repeat
