The US Post Office is crunching to get all those holiday packages delivered on time.
Wednesday's blizzard halted all shipments statewide and post office workers are paying the price.
Hundreds of post office employees around the state are volunteering to work overtime.
Some are even giving up their Christmas Holiday just to make sure everyone else's holiday plans are complete.
They're doing that by delivering one package at a time.
Bob Podio, Pueblo's Post Master says, "We're gonna try to deliver four days worth of mail in two."
Four days worth of work, cramped into just two days.
Podio says, "Anything that looks like a Christmas package we're gonna try to deliver in the next two days."
Post office workers say, they can pull it off.
Post office worker Jerry Goss says, "Everybody here wants to get the packages out."
Denver being the main hub for Colorado, was shut down for nearly three days because of the blizzard.
That crippled the flow of mail.
Podio says, "Oh we're talking hundreds of thousands of packages."
Everything was frozen in place.
Nothing was going in or out.
Post office worker Jill Willis says, "Right now we're trying to catch up."
Trying to catch up on all of those holiday boxes that are wrapped so carefully and filled with special things.
All of which are now on their way to their destinations.
Post office worker Oscar Sosa says, "There's a lot of trucks coming down."
Workers say it's a well oiled system that's making all of these deliveries possible.
Goss says, "We've had people thank us."
After all, workers say, they wouldn't want those little kids looking forward to their presents to be disappointed.
Willis says, "It would be terrible i think it would be very very sad."
The US Post Office is asking folks to be patient.
They say they wish the blizzard hadn't hit when it did.
Workers say there should only be a hand full of gifts that don't make it by Christmas day.
