When I first saw this photo I thought it looked like a giant oriole nest! But since it was fashioned from barbed wire I think the homeowner might be sending a barbed message (sorry, that was irresistible!) to say: "No Bills or Junk Mail, Please!" Photo courtesy of David Sewell.
I'm a transplanted New Yorker who loves the Tucson climate. On New Year's Day I have a bit of fun calling my (snowbound) east coast friends to announce that I'm drinking coffee while sitting on my patio. (:
