I think I have a Marauder’s Map of my own. It’s an excellent map with all the extra notations and incidental keys. I don’t recall where I put my invisible cloak. I think my mother took it with her instead of leaving it for me. Which explains the tap on my shouler a few weeks ago...

I read recently that a cane or a wheelchair (Post 1328) could also confer invisibility.
Ya gotta use the tools available!
