A former hermit in New Hampshire who went back to live on the wooded property he was ordered to leave realizes that his time there is drawing to a close — but he appears willing to keep fighting against his removal for now. David Lidstone, who just turned 82, failed to show up for a contempt of court hearing Thursday in his tug-of-war with a Vermont landowner over a patch of forest near the Merrimack River that he’s called home for 27 years before his cabin burned down in an accidental fire. Given his history of not appearing at hearings until he’s arrested, a judge on Thursday said Lidstone would face a $500-a-day fine if he doesn’t leave the woodlot by April 11. A judge issued an injunction in 2017 for “River Dave” — as Lidstone is known — to leave after the landowner, Leonard Giles, sued him. But there have been delays in the case: Besides the pandemic, Lidstone hasn’t always shown up for court and he’s been in and out of jail as he resisted the injunction. Court records say the undeveloped property has been in the Giles family since 1963 and is used for timber harvests. Lidstone had claimed that years ago, the current owner’s father gave his word — but nothing in writing — allowing him to live there.
