Update: Cache has been replaced after being muggled - you are now hunting for a micro!
There is parking very close by, so it should be an easy park and grab. Just watch out for muggles (and security) - it may be easier to grab this one of an evening or weekend.
Have a seat and enjoy the view of the USQ buildings, gardens, and driveway of flags.
Well done to Davinells on F2F rights!
