This is a Nano cache.
The 5 flag poles laid right outside of the Star Ferry Pier, it's
a very popular local landmark for people to meet up.
It should be rather obvious where the logical cache location is,
but since this is a high muggles area, retrieving and replacing the
cache might prove to be difficult.
PLEASE BE VERY STEALTH and make sure no muggles see what you are
doing.
Oh, remember to bring you own writing instrument and write
small.
