I had a battery operated mower for Bride the Second's house in Crystal Beach. A 'postage stamp' of a yard. What made it bearable was the second battery that came with it. I was able to tackle a larger lot when the neighbour's mower gave out. I imagine in the seven or eight years that capabilities have improved.
Ms. Couric seems to have been afforded any number of platforms (network news anchor, talk show host) without greatly gathering audiences. I fully expect some network executive will have her throwing dice on the revival of 'High Rollers'.
