In another Forum I posted that Vito could certainly afford to pave the mall's driveways, but instead opted for gravel.
In the scene following Carlo's murder, Michael and several others walk across the mall and one can clearly and loudly hear their shoes crunching on the gravel as they walk. I always thought that was, at the least, hilarious. I'll bet that post-production added in the crunching emphasis. But why?
