Why move the money at all (***spoilers***)?
So...Josh hid the money at the dump. Nobody else, except maybe the other 10 (9 survivors), knew where it was; in fact, nobody (besides Santos) even knew who pulled the heist. The money never would have been found. The only problem is, Santos wanted half, in exchange for his silence. He was going to call the police if the guys didn't play ball--*regardless* of where the money was hidden.
In other words, Danny & Co.'s challenge was to avoid being ratted out to the authorities...NOT to prevent the money from being discovered. So what would they have really accomplished, if the money HAD been successfully smuggled out of town (inside Tony's casket)?
Am I missing something?
