12-Mar-2000 -- I travel back and forth to Philadelphia, where my
daughter is a student at Temple University. When I noticed that there was
an unclaimed confluence near my travel route, I made up my mind to visit it
the next time I had a chance. It helped that the confluence was easy to
get to: on a golf course.
I had allocated plenty of time to find the exact spot of the confluence,
and to see my GPS unit reading all those zeros. Although it was mild when
I left home in the morning, by the time I got to the area of the confluence,
it was windy and raw, and I was not dressed at all warmly enough. To my
surprise, there were also golfers out hitting balls all over the place and
giving my funny looks.
I managed to park my car by the side of the golf course, a couple
hundred yards from the confluence. It took me a while to get the hang of
navigating toward a given reading, especially when I was also trying to stay
on the paths as much as possible. Just when I would get the numbers all
down to 0, the reading would jump 5 or 10 in the least significent digits,
and I would walk about trying to get it down to 0 again. Eventually my
hands got so cold I was having trouble working the camera, so I returned
to the spot I had wandered across most frequently and declared it THE
SPOT. According the the "final" reading taken there, it was
within .00021 degrees of true, or well within the GPS accuracy. I now know
the disadvantage of not having an "averaging" GPS.
THE SPOT is at a little tree at the end of a path, near one hole and the
next tee-off spot. Pictures one through four show the view from this point.
Picture five shows THE SPOT from 50 years away (behind the trees and a
little right of center). Picture six shows a view of the golf course from where
I entered, near where I parked.
