The economy's down. Water prices are up. It's time to get yourself to a "Build Your Own Rain Barrel Workshop!" It may be not be the first thing you think of to cut your bills, but over time, reuse of rainwater can actually save some cash. (Just think of all the water you douse on your garden in summer heat.) Arboretum's Conservation Director, Joe Blanton, teaches how to construct and install your very own rain barrel in this four-hour workshop.

BONUS: Rain barrels are environmentally friendly and increase your chances of attracting environmentally-conscious individuals.
