No one told me that rain barrels could be addictive.   I started with one to go beside my front porch.  With it’s forty gallon capacity I figured it could easily manage the watering of all my plants on and around my steps.   It worked so well I bought two more and installed them at either end of the house.  Now I collect enough water to do my entire front yard flower garden.  Of course the neighbors have started calling me the rain barrel man.   I have to laugh when they do because over half of them have asked me where to buy them.
