I placed this as part of a 5 mile loop, but it can be done as a drive-by.
At GZ you will find an interesting old boundary marker.
A while ago I was looking at the map of greenspaces around Shrewsbury and thought I must be able to make a nice loop from my home in Frankwell and visit some of these. By the time I actually got around to it I had a nice stash of cache materials so filled my backpack to make a day of it.
