Rooney's upped the ante on her new watery lair. It includes a steel cage to keep out all muggles.
This cache is small enough to be small, but big enough to contain small trackables and geocoins. Rooney loves treasure.
Rooney would prefer you wear your scuba gear, but it's not necessary. Rubber boots might help if you don't have Level 3 agility.
Bring your own pen.
