If you have worked through Seasons 1 through 3, you know that Season 4 is where Bob truly hits his stride. The landscapes get bolder, the techniques get smoother, and the "happy accidents" become legendary.

Go purchase the season legally. Grab a cup of coffee. Load up episode one ("The Mountain at Sunset"). And remember: There are no mistakes, just happy little accidents.
