Well, the first day that I got all my wireless equipment, I actually went for a bit of a wardrive around my neighbourhood, and found the following (interesting) details;

• 20 different SSIDs scanned
• 35 unique MAC-addressed nodes scanned
• 8 WAPs encrypted with WEP [23%!]
• 10 WAPs using what appear to be default SSIDs [29%]

I really want to get a GPS device of some sort so that I can start mapping these points properly, because at the moment all I can really do is either try to map them manually, or just live with only the details of what is found, rather than where it was found.
