    Re: GPS selective availability

    Geoffrey,

    The UK is not unique in having benchmarks.  My son-in law is a surveyor and uses many such benchmarks ( monuments ) in his work.  He and his co-workers will update the position information on older monuments that they find in remote areas.

    I own land in a remote area of Wyoming that has a 1940's bronze plate set in an concreat pillar.  My son-in law and I remesured the cooridants using the latest gee-wiz GPS equiptment and know the position down to inches.  So, if you are ever near Chugwater, Wyoming and need a fix, let me know.  :-)

    John H.
