Well we're all back now, safe and sound but to a chillier England which is intermittently being covered in snow. Or as Folly put it 'back to drinking warm beer in a cold place rather than the other way around'.
Although we didn't quite reach the 'Dead City', we're never the less very pleased with what we did manage to achieve. As detailed maps of what lies ahead simply aren't available, the GPS data we obtained will allow us to accurately purchase the next best thing, satellite photography. As this is expensive and sold by the square mile, we can now specify precisely what we need which will make it significantly more affordable.
