Tom, this is getting dangerous - I'm rapidly getting addicted to your blog - so thank you! And also thanks for giving me the impetus to finally get my finger out and set up my own blog - it's going to be no-where near as interesting as yours - but hey, everyone has aspirations huh? I've ordered your book to read on my hols - tho somehow I don't think it's going to last me 2 weeks - more like 2 hours!!
