These purely fun aspects are for those who have seen the film more than once.  I'm up to four times, but  what else have I missed, anyone?

 The questions:

 1. What are the two letters spelled out in rocks on top of the old Plymouth, and what do they mean?

2. The titles credit the actors playing Patricia Millman and Dan Millman, Sr. In what scene in the film do they appear?

3. What job did Fred the Finisher perform?
