When in danger of receiving a slap
From a storm which can alter the map
Just fill a basket
Atisket-atasket
With fistfuls of handy riprap.

Note: The heavy wire baskets [often filled by hand] to contain the riprap are known as gabion baskets. For photos of gabion baskets filled with riprap, pls go to:
