A nice email arrived today:
Having purchased and read ‘The Natural Navigator’, I wanted to express how much I enjoyed and got from the book. Being in the outdoors a lot, I was able to go out and look for the features in the book and it amazed me how often things would pop up here and there. My favourite was I told staff I was working with on a D of E expedition to look out for signs of puddles on the southern edges of paths running east-west. They were a bit sceptical but when they started looking they were everywhere!
