I just ordered our tandem rain barrel from rainfordane.org. (part of sustaindane.org) I wanted 2 of them and they offer a tandem barrel for $35 more than a single so that is awesome. My friend Susan got beautiful barrels at a local hardware store (I think...where exactly, Susan?) and I got to see it in person the other day and knew we had to have something soon. They are so cool! I wanted to make ours, and got a free barrel from a local car wash, but just wasn't sure it could be cleaned enough to be safe...so we ordered them and it's DONE. Feels good, can't wait to get them!!
