I found it difficult to match up many places that I flew over last Tuesday with my route in the other direction. Is that Ostuni? What lake did I photograph? And where did I cross the channel? Is that Boulogne? What I do know is that what took me 5 weeks to do north to south by bike took Ryan Air 2 hours and 55 minutes to do south to north (cue fanfare!) by plane. I preferred the former method.
