Another wonderful story, @bruno-kema. You create a circumstance in which the reader wonders if the woman has truly visited Jason's tent, or if Nate was having a little fun. The suspicion in this reader is that the latter explanation works.
One thing I noticed as I read your story and tried to figure out why it has so much energy (typical of your stories) is the use of active verbs. For example, the campers hurl their backpacks. Nate's chest puffed with confidence. Fear churned his stomach.
I think it was Stephen King who suggested that adverbs weaken a story. The verb should be strong enough to carry the action. You do this very well.
Just thought I'd add a bit of textual analysis to my comment. Might help other writers to understand what you achieve when you write. I enjoyed your story very much.
