I had a look a the 'Photographic Guide to England' last night and its very, very nice. The price at £99 is nearly as heavy as the weight, but it was on offer. I think it was reviewed in this months 'Pilot'
The detail is amazing, I only had a brief look at my local area but found my house and workplace. I think it will help in X-country navigation, but for anyone who likes maps, this will add a whole new dimension.
As the flying fund is quite healthy due to weather-induced ground-hugging, I might go out & buy it, especially as it was on offer.
