If you put a new list on a route the same day as an old one, the old images may still be there. People call these leftovers ghosts.
- For lists you want to keep for good (the presidents), give them their own route and leave it alone.
- For practice and one-time lists, rotate several routes, and give each one a day or two to clear.
- Make new images extra vivid so they outshine any ghost.
Key idea
Keep permanent lists on their own routes. Rotate practice routes.
