flickr One advantage of travelling only with a plastic bag of not alot is that you get to go book shopping. So it was at Borders that I came across The Cloud Spotters Guide by Gavin Pretor-Pinney (duh! it's cheaper at Amazon ). The book is excellent, and I must say I've become a bit of a spotter, so much so that Paul went as far as to call me a freak on the last drive home yesterday. [ www.cloudappreciationsociety.org ]
