Santa, slide down my downspout

Santa, all I want for Christmas is some rainwater.

Rain barrels are hot

I hadn't thought of this... If you're in a place which doesn't get as much cold weather as Minnesota does, you can use your rain barrel to protect your outdoor potted plants.  The water in a barrel tends to stay warm at night, so having potted plants near or on the barrel helps protect them from frost, especially if you cover it all with a tarp at night.
