A couple years ago, a severe ice storm hit Nebraska, knocking down trees and power lines and coating everything in sight with a thick layer of ice.  For several days, everything was so slick I could barely get around my yard to clean up fallen tree branches, let alone get out to nearby prairies for photography.  Fortunately, my backyard prairie garden was still accessible to me, and I was able to get a couple of decent shots, including this one of rigid goldenrod seed heads.
