We are pretty far from any bank (so, no need to look out for bank robbers), and this is definitely not on an island - BUT, their is a "gulf" between the parking lot and where the cache is located.
Well, and come to think of it, there are no missing chums, but since this cache was hidden during "social-distancing" and times of quarantine, there are "missing" people from this beauthiful park.
Help Frank and Joe find THIS MISSING CHUMS (Hardy Boys #4).
(plenty of room for the good kind of bugs!)
