<DIV dir=ltr><FONT face=Arial size=2>I believe you missed the point Mr. Bishop.</FONT></DIV>
<DIV dir=ltr><FONT face=Arial size=2>Nobody is claiming that the type of feet make any practical difference in the cave.</FONT></DIV>
<DIV dir=ltr><FONT face=Arial size=2></FONT> </DIV>
<DIV dir=ltr><FONT face=Arial size=2>HOWEVER, not everybody gets to do their own thing with an isolated survey that nobody cares about.</FONT></DIV>
<DIV dir=ltr><FONT face=Arial size=2>Some people have to deal with agencies and their legally mandated requirments of throwing significant resources onto their local State Plane Coordinates, and matching their local control points. And for those which feet are used can make a difference.</FONT></DIV>
<DIV dir=ltr><FONT face=Arial size=2></FONT> </DIV>
<DIV dir=ltr><FONT face=Arial size=2>For example, the Colorado North State Plane Coordinate system has an origin OVER TWO MILLION FEET west of a lot of the region covered in the zone. In 2,000,000 feet the difference between the feet add up... and the difference is large enough to be measured by even a drug store tape measure.</FONT></DIV>
<DIV dir=ltr><FONT face=Arial size=2>Maybe you were going for humor with your comments, but the difference between 2,000,000 "International" feet and 2,000,000 Survey feet doesn't need in invar tape to detect.</FONT></DIV>

<DIV dir=ltr><FONT size=3>It seems to me if someone wants to play by the technical legal rules, they should be allowed to without people arguing against it.</FONT></DIV>
