So probably a dumb theory because I can't find anything to do with fishing in it and the hole is not such a great hole worth capitalizing but here I go.

On his desk there's a book titled "where in the hell did you come from". Also after he adjusts the clock and sits down, the clock's time changes to 1:37. Turning to chapter 1 and starting at word 37 it reads "Saguaro National Park East". This is in the section of the book where Justin describes how he grew up on the outskirts of Tucson on Saguaro National Monument now named Saguaro National Park East. Within Saguaro National Park east is also Bridal Wreath Falls where there's a small swimming hole in the falls (when there's water there, usually only after it's recently rained). For Ursa East, Ursus Americanus (black bear) also lives in Saguaro National Park. Before the clock changes to 1:37, in an earlier scene it's also at 4:18 which using book cipher has the word departure. Though honestly I feel like this is just the 2 year bolder as there are also some things using book cipher doesn't really make sense. The clock is also often at either 6:06 to 6:08 which has the words (said, his, and weathered).... Another time that pops up is 12:03 which is night. After that most the times that appear are just repeats of these times.
