Hi, I wondered if any of you had seen this article from 21st February 2019 over on the Mirror website:
"Lego washes up on UK beach 20 years after 5million pieces spill from cargo ship"
Apparently, Tracey Williams, who regularly collects the Lego, has a Facebook Group on the subject, called Lego Lost at Sea.
Also, here's their Twitter account.
I thought it was an interesting article and made me want to go down to Cornwall to hunt for lost Lego Castle parts. They must be saved!
