Torn banknote rejected at the national park ticket window — where do I swap it without missing the jeep?

Ticket windows often refuse badly torn or taped notes. Reshuffle clean smaller notes from your wallet first; ask if card is accepted that day if the board shows it. A shop outside the gate will sometimes swap a torn note if you buy something small and the note is only lightly damaged — banks are slower and may not beat a jeep departure. I will not invent a park ticket price as gospel. Keep a few crisp mid-value notes dedicated to counters and you avoid this scramble next time.
