A Florida couple surveying damage after Hurricane Irma last September found a message in a bottle, sent more than three decades ago by a class of children in Scotland, FlKeysNews reported.

On Sept. 29 last year, Ruth and Lee Huenniger were walking near their Key Largo home, inspecting street lamps. Ruth found a plastic bottle lying near a chain link fence and noticed there was a note inside.

“We are learning all about pirates. We would like to see how far this message goes. Please write and tell us where you found this bottle,” the note said.

The note was signed by Class 2/3, Chapelpark School, Forfar, Angus, Scotland, FlKeysNews reported.

The Huennigers decided to write back to the school, whose class sent the bottle hurtling into the North Sea in the 1980s, WSVN reported.

“I thought, ‘Let’s see if this gets all the way back to Scotland,'” Ruth Huenniger told WSVN. “I mean, I’d never heard of Forfar.”

“Your message was found in Key Largo, Florida, USA, on Sept. 29, 2017,” the new note read. “Hope this was a fun experience for your class.”

This time, the note was sent through the mail. On Oct. 23, the Huenningers received a letter from Fiona Cargill in Scotland. The retired teacher said her class had written the note sometime in the 1980s, FlKeysNews reported.

“We forgot to put a date on the letter, but would you believe it, that bottle was sent on its journey more than 30 years ago,” Cargill wrote. “The pupils who took part in this will now be in their mid-thirties!”

Chapelpark Primary School closed in 2008 and is now an apartment building. The postman who was given the Huennigers’ letter for his route knew this and delivered it to the town’s new school, Whitehills Primary, FlKeysNews reported.

“The staff did an investigation and discovered it was my class,” Cargill wrote. “I retired from there just over a year ago and was so, so excited about this wonderful true life story.”

Cargill said her class of children ages 6 to 8, had studied pirates and decided to send several bottles.

“They covered them with sticky plastic to keep them from getting wet, put them in bottles and then got a fisherman to put them in the North Sea,” said Cargill, who added there are at least three more bottles that were thrown into the ocean.
