Although rainbarrels may not be available on most hardware stores, you can find lots of websites that sell rainbarrels. I fully agree with you Kim, not all people know what rainbarrel is (and would you believe that they are actually called "water butt" in the UK? hehe..). And as what Kim said " you can also make your own rain barrel. It actually quite simple. All you need is a container to collect the rain and some basic carpenting skills. Thanks for posting this. Enjoyed reading it.
