A guy's wife (husband was there physically, if not in spirit) got quite animated because we had set camp in a vacant spot (theirs, apparently; we hadn't made reservations) which they arrived to after dark.
Having received a call about us being aggressive and otherwise generally inconvenient (unfair, I thought, overhearing as I packed my boat in the dark), the rangers treated us very decently. Don gave us an unoccupied lean-to and some firewood without charge.
Thank you, Don!
