SARK, ENGLAND — The rain had stopped, which renewed my enthusiasm for exploring tiny Sark, an island which is part of the Bailiwick of Guernsey. Smallest of the Channel Islands and only accessible by boat, Sark is unique in that it is a fiefdom granted to the Seigneurie of St Ouen in Jersey way back in 1565, with the proviso that he keep the island free from pirates.
