How much time....
Do you think passed between Andy's escape and Reds parole?
On one hand, Reds dialogue about how the prisoners would tell stories about Andy indicate there were at least a few years. On the other hand, when he reunites with Andy, he has barely started working on the boat which makes it seem like he hasn't been there very long.
If I were to personally guess, five or six years seems about right. Andy would have to acclimate to his new environment, spend time laying low and getting comfortable in his new life, acquire a hotel, do whatever work needs done on it, and then he could focus on the boat to take his guests deep sea fishing.
What do you all think?
