Our Mustard Seed Walks group took advantage of the fine autumnal weather to enjoy a seven mile walk down Dr Blackall's Drive and down the the River Dart. What goes down must come up unfortunately and the second half of our walk was spent regaining the height we had lost in the first half - a fine example of the exchange of energy: potential, kinetic, thermal, chemical etc. But what a lovely walk in God's beautiful creation with excellent company.
