UPDATE May 12, 2023: I replaced the container and it can be retrieved without a magnet, although it will still be easier with a telescoping magnet. The container is now a micro.
There was a cache at this location several years ago. I thought it was a good spot and so I placed a new one. You will need a tool to retrieve the container.
This is usually a quiet street and muggles will normally not be a problem. Provide your own calligraphy instrument.
