SPOILER ALERT! Great action flick with well-written characters, often compared to "Billy Jack" and "Walking Tall." Fistfights and tough guys galore, Kay Lenz looking adorable, what more could you ask for? Climactic scene of Jan-Michael Vincent's "Blue Mule" diesel tractor truck barreling through a guard shack and becoming airborne is one of the most memorable bits of 70's action cinema. Highly recommended by me.
