The 13th Juror tipped me off to a story about a squatter in London who won rights to a piece of land where he'd lived for more than 20 years.
70 year old Harry Hallowes, originally from Ireland, was broke and "sleeping rough," as they say in the UK, when he settled on Hampstead Heath. The Land Registry awarded him the land after Mr. Hallowes proved he had lived in his 12' by 8' shack for more than 12 years. (How could they resist the alliteration?) The land is valued at two million pounds.
