Saw a geology report that said the Pacific Crest Trail near Stevens Pass lost over 50 yards of path in a landslide last spring. They had to reroute the whole section.

That "hollow feeling" after hitting a goal is too real. It made me remember this old sci-fi book, "The Sparrow", where the main character achieves this huge thing but it just wrecks him. I read it years ago and still think about how the ending just sits there, all quiet and awful. It's less about the plot and more about that specific mood of success turning to ashes.

My old workshop leader always said give them the haunted house, not just the ghost. A little setting gives everyone a shared starting point to get weird from.
