Janet's morning walk seemed unlikely the previous day with more rain forecast. However no rain fell although a few parts were still wet from earlier rain. A very pleasant walk from Trotton to the hill above Rogate and back again with lunch in The Elsted Arms. Nigel was quick to hear a yellow hammer perched high in an oak tree. The concrete lumps in the field on Habin Hill turned out not to be a gun emplacement nor a nuclear shelter, but probably just an old water reservoir. We later crossed Habin Bridge, a scheduled Ancient Monument, built by monks from Durford Abbey in the 16th Century.
