My man used to live in Minnesota, so I've been hearing a lot about snow (even as early as on Halloween one year!). Likewise, as is lizelle's hubby, a technical engineer of sorts, he would no doubt instantly take to the idea of installing such a highly sophisticated waterbarrel (including concreteslab) with great precision with great precision in our garden. The amount of rain that falls here would fill it in a day or two, no sweat. However, it would fill half my garden and leave little room for sunflowers, our favorites this year.
