Here's a good tip too:
If you want to find something on Google Earth, you can use the co-ord converter at Streetmap:
http://www.streetmap.co.uk/streetmap.dll?GridConvert eg, type in your postcode and this gives you the Lat and Long for it - use the ones in brackets and put them into the "Fly To" box in Google Earth (top left) in a Lat,Long format - eg, 52.077679, -1.021446 ) and it goes straight there.
