I used to carry a compass in the car to help me navigate. I did too, car version mounted on dash, with a battery to light up at night. And I used it so much I decided to use a NiCad rechargeable. Immediately I wanted north, so turned left and the road was heading south, turned left and it was still south, turned left, and left and bugger me! I am an Electronic Engineer, and I KNOW nickel is magnetic - never thought! I was permanently on a S by SE heading. Doh! Post Codes 'Probably' because it may use the nearest point on a road - don't know. The area is based on the volume of mail, and Village Halls don't get post! Worse VHs usually publish the caretakers' contact details AND it is their post code! http://mister.red lists a lot of events in VHs and Goggle Earth is invoked many times to verify OSGR and Post Codes (not always the same 1 metre square for my website)
