Friends kept telling me that Google Earth is a must. I did a search on Google and this was the top of the results page. Just thought I'd let you know that this one is a scam. I haven't read any warnings about it anywhere. According to a community group Google are aware of it but that hasn't made any difference.
Google Earth is great - I don't know if you will be able to see the Google Earth date on my screen-shot, but it is April 2008. But anybody wanting to, should only Google for 'Google Earth' without the 2008!
