Yes. The pending leap second has me very scared. It is the Y2k bug of 2008. :-)
Sorry, that is a tilde, not a negative sign. Meant as "approximately" 791 meters, although I may be using it completely wrong. The real value (mean average) is 790.83 meters for the Sure Electronics GPS. Sorry for the confusion. --- On Sat, 12/27/08, Richard W. Solomon <[email protected]> wrote: From: Richard W.
