Typical scene at the end of the day on the beach at Sorrento , too chilly by 6pm for anyone but surfers to be in the water, in summer the scene will be so very different with families swimming until quite late to cool down after the hot day!! I didn't actually see what made the tyre tracks, I'm guessing one of the surf life saving vehicles (an alien presence sounds way more exciting, but perhaps a tad less likely!!), looks like it was going round in crazy circles but I'm sure there was a plan in place somewhere along the line.....!! Keep safe, I know that's easier said than done for friends on the East Coast USA with the prospect of Hurricane Irene on the way, will be following news reports ....!!
