FORT MYERS, Fla. - Postal workers hard at work on this, the busiest day of the year for them, and they won't be done until the wee hours of the morning.

"The middle Monday of December is historically always going to be the heaviest mailing day of the year in any state," Collier Postmaster Richard Barber tells WINK News.

Just like Santa's little elves hard at work, the US Postal Service is in overdrive to make sure any holiday cheer sent through the mail reaches it's destination on time.

"On an average day we'll deliver about 1.3, 1.4 million letters into the tri-county area; Lee, Charlotte, and Collier county," Barber explains. But, on this day the processing center in Fort Myers blew that number away by delivering 2.4 million letters in just the morning.

The workload isn't expected to decrease until after Christmas. Barber says the best tip for mailing holiday cards and packages is to avoid Mondays and mail as soon as possible.
