Dependent upon a few things happening over the next couple of months, planets aligning, etc, I've thought of treating myself to a week or two sitting on the fence in Western Europe in September or October as a change from yet another grey Typhoon at Coningsby, etc.
Does anyone have any suggestions for bases within, say, a day's drive of either Calais, Caen or St Malo that offer reasonable views and photography prospects (pus a record of relatively civilised policing!) that I could string together into a driving holiday. Luckily I'll be on my own so I don't have to dress it up as a cultural, sightseeing or shopping trip!

I know I can spend time on Google Maps, etc to see what likely targets look like from above but nothing beats any personal experiences or tips that can be passed on.
Thanks in advance!
