“I’m a woodsman.” So what? I think “I’m a sailor” might carry more weight in this situation. Hey, maybe Popeye could make a guest appearance. Anyway, it’s been a week and they still have not left the dock! Furthermore, exclamation points are running riot!
But this is the local river or lake (not sure which), so Mark’s heroic pledge seems as pointless as Cherry’s need to track their movement. Oh, it’s humor. Well, we are at a juncture in the plot. If this were a book, we’d be reading the last page of a chapter where somebody states, “So, what could go wrong?”
The final narration box is annoying. At most, it needs a Dick Tracy style “Hidden Backpack Tracker” with arrow.
