What brings more pleasure than swinging lightly in a shaded summer breeze? Not much. Maybe a small basketball (as see in the picture). But this need not be just a container for a hammock. Think of things you constantly bring in and out of your house, garage, shed and into your yard. Any of these things could fit into a custom made storage box and fitted to a tree in your yard (or to a 4x4 post set in concrete wherever you like). The two big uses for this kind of container that I can think of are for yard games and garden tools. If you and your family have one of those badmiton/volley ball sets, croquet sets, horsehoe sets or whatever then this might be a great storage solution for you. If you enjoy gardening then a well placed box with your shovels, hoes, and miscellany might be a time and energy saver. Could also be used to hold garden hoses, drip irrigation hoses, loads and loads of things.
