"Canal Zone"
Canal Zone is the absolute best canalboat ride you'll ever have taken! I have rides planned to go through other worlds, but this goes several ways across BardoTown, and it's really something amazing. It makes a powerful and energizing meditation, just to sit and watch it. You don't need to do anything, although you are always able to get off and back on the boat anytime you want to explore something close up or from a different perspective.
