$199,990 -- That's the difference between the value Suffolk County placed on a sliver of land in East Hampton and the price it ultimately fetched. The county initially offered it for $10. Two adjoining landowners from Manhattan really, really wanted it -- arriving in Hauppauge for a face-to-face auction that ended at $120,000. All for an 1,885-foot strip only a foot wide, but providing access from Montauk Highway to pristine ocean beach on the exclusive Napeague stretch. The rival neighbors may have pushed the price ridiculously high, but surely Suffolk started out too low.
