I GOT A MOON BOOT for my crook foot today - later, looking out the window at home i see two big goannas, nose to nose looking like (sorry for the anthropomorphising but) like they were experiencing an electric kiss, vibrating - it was amazing, a shock and a thrill. 
camera!   moon boot!  aghh!   i made it clumsily up the steps and across the room and grabbed my camera and they were gone.
