Levees

I am just wondering what one has to do (or better, not do) to be a levee-builder. Or maybe those things don't work! We had the levees in New Orleans bust open a few years ago and now the Mid-west looks more like Venice than anywhere else. Or maybe folks weren't prepared for the end of the world this early (thanks Al Gore!). That's it...just a quick note to encourage folks to save the planet.
