Thanks for posting this Mark. For those who are interested the audio diary of my journey to Germany, including that clip from Cologne, can be found here: http://audioboo.fm/tag/rjde11 ; whilst my guide dog training diaries are here: http://audioboo.fm/tag/guide%20dog%20training%20diary . Both obviously appear backwards, so you'll need to navigate back through the pages to find the start. I'd be interest in people's comments on the individuall Boo pages.
