I believe you don't K quite F enough; back when I was more involved with this stuff I think there was one instance (or possibly two) where a zipcode straddled a state line. But the question would only need to be asked in the rather unlikely case that such a zipcode was entered. The situation was mostly caused by local geography; the zipcode I remember covered a long valley in a very mountainous area; the state boundary ran roughly down the center of the mountain range, but the extreme end of the valley crossed into the next state. The only roads to that area, though, ran up the valley, so it made sense to have the postal delivery area be based somewhere where there were actual roads leading to the addresses. -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
