The beauty of the Christmas season slowly fades as families look forward to the promise of a new year. It isn't chilly weather, so hearts are warm. The Times welcomes readers to send us their best photographs. No matter whether they capture the brisk wind, a sunny smile, brilliant color, an unusual image, person, place or thing, please share. Photos can be of any subject, but we especially like people.

Please send photographs to David Adlerstein at Dadlerstein@starfl.com. For more information, call 653-8894.
