Thanks for attempts to bring some sanity to this thread Sebbie but are we really at the end of the mystery?
We seem to have found a red speedo on Jason somewhere along the line but it was Dad Thornton who performed the spectacular winning dive in the contest, so was he also wearing red, as specified in the original enquiry above?
The filming locations were all CA and not AZ and the storyline makes no mention of a character being in trouble over a photoshoot for a calendar.
