SO George and Barbara (or Babs as some of us know her) are in our midst, and by all accounts enjoying the splendid views across the harbour afforded from the Regent where they are billeted - the choppy seas yesterday probably giving a homely reminder of Kennebunkport. So cosily domesticated are the Bushs that when Keeping Posted dropped by the Regent, we thought that the couple's inseparable canine companion - ex-First Dog Millie - was here with them. For a black dog was sniffing around the lobby and getting the attention that only VIPs are accorded. As we attempted to approach Millie to tell her how much we enjoyed her book we were quickly put right by Regent PR manager Tim Cumming who informed us that it was a sniffer dog on the look out for any explosive devices that may have been left around to coincide with the presence of the former US president. And with Chungking Mansions, the reputed safe-house of questionable visitors to town, just down the road one can't be too careful.
