Very true. My great-grandfather's and grandfather's (now 97) generations were perhaps the greatest changes in a single lifetime. They went from an age when (from time immemorial) farmers broke ground with oxen or horses to the mechanical age to landing a man on the moon (in my great-grandfather's case). That is an incredible explosion of technology. If you were graphing it it would be astounding how much it has spiked. -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
