It was a beautiful morning in Edinburgh; no wind, sunny and very pleasant. We decided to get on our bikes, (not to look for a job), and go down to Silverknowes and Cramond. There had been a ground frost overnight, so there were still some slippery bits in the shade. However, the views and weather meant we could enjoy the ride. At Cramond, there is a causeway linking the mainland to Cramond Island. During the second world war, a submarine defence boom was built of concrete blocks. Along the top of the pillars was placed a ring to run a wire. These pillars stand proud of the water most of the time, and the tops are a favoured spot for gulls. In the background can be seen some of the many WW2 fortifications on the island.
