Google Maps - Wow, Now That's Impressive!
I am so impressed... do yourself a favour and have a look. You can drag the map around (or the zoom feature), rather than clicking on arrows or '+' and '-' signs and waiting for the page to re-load. When you've maneuvered the map to where you want it, you can click on 'link to this page' and the URL turns into a fixed position & zoom height on the map.
This (by far) puts to shame any map website I've been to. Can you tell I like it? :-)
