WIFI - 4 from 17

I thought I'd try a little experiment today. I had to go and feed S's cat this morning and then return home via the post office to pick up a parcel - a walk of about 10 mins that involved a basic lap of the village. So, I set my wifi sniffer up on my TyTN and left it running. I caught 17 access points in total and, surprisingly to me, only 4 were unprotected. So, is the world becoming more secure? Well, by ratio I think so....but a couple of years back there were only 4 access points in knebworth and they were all unprotected! It is interesting seeing what people have named their routers though - everything from the number and road of the house it is in to 'The OC':)
