A quick cache n dash here, you may park at GZ.
But beware from early evening there will be a high number of muggles. (you might want to bring some cash if you are hungry or fancy a drink).
Container is a small click lock box big enough for small swaps and small trackables, with log, pencil and an FTF keyring for the first to find.
*** Congratulations to Cannonfodder32 for FTF ***
