The Mens Room at Pacbell Park

Hi Don,

I'm always interested in your two cents!

The only problem with San Francisco being the center point of a circle is that San Francisco, as you well know, is not a point, but rather an area.

I suppose a predictor could simply look up, and accept, the lon/lat as defined by geographical sites available on the web or something like that. Not sure if the lon/lat as defined by Getty is the geographical center of the city, city hall, or the mens room at Pacbell Park ....

In the end, the predictor would have to provide a lon/lat pair as a centerpoint, unless anybody has any better idears.

San Francisco
Lat: 37 46 00 N degrees minutes Lat: 37.7667 decimal degrees
Long: 122 25 00 W degrees minutes Long: -122.4167 decimal degrees
