Just a word of caution for those convinced by all the enthusiastic reviews here (like I was). This book makes a nice read and would be a good addition to the coffee table, but can hardly be useful for any camping trip which lasts longer than a weekend.
Even though I very much agree with the philosophy of 'comfortable' camping, the advice in this book is not really practical. Just an example: replacing the sleeping bags with pillows, duvets and the rest as the book suggests will not only fill up your car boot to the brim, but will also turn into a nightmare if you get water into your tent. Unless, of course, you are on a weekend trip and can just turn around and drive home.
Similarly the recipes (which are great on their own) do not really differ from what you may find in a 'normal' cookbook and certainly assume that you always have access to fresh ingredients and a suitable place to store them, not to mention the unlimited fuel and cooking equipment. Once again, great for a weekend-long picnic, but not really practical for a week of driving around Scotland.

All in all, it's a nice book, but don't get mislead by the reviews: it's great to take on a picnic, but is useless for a longer trip.
