Last week I took a camping trip to Sequoia and King's Canyon National Parks, where (among other things) I ran a Puzzle-based interpretive program at the Grant Grove Visitor Center. We had about a dozen people total, half of whom stayed around for 40 minutes (twice the scheduled program length) to better work on their Puzzle projects!  Below are some pictures from that program.
