CANTERBURY, N.H. — For almost three decades, 81-year-old David Lidstone has lived in the woods of New Hampshire along the Merrimack River in a small cabin adorned with solar panels. He has grown his own food, cut his own firewood, and tended to his cat and chickens.

But his off-the-grid existence appears to be at risk.

“River Dave,” as he’s known by boaters and kayakers, is behind bars after being accused of squatting for 27 years on private property.

As the owner of the land seeks to tear down the cabin, Lidstone has been jailed since July 15 on a civil contempt sanction. He faces a hearing Wednesday.

“He’s just a really, really, big caring guy, and just chooses to live off the grid,” said Jodie Gedeon, an avid kayaker who befriended Lidstone about 20 years ago.

She and other supporters are trying to keep him in his cabin in Canterbury, including organizing a petition drive and working to collect money to cover property taxes.

“It really is about humanity, it really is about compassion, empathy … he’s not hurting anybody,” she said.

Gedeon and other supporters came out to a town selectboard meeting on Monday. Board members said the town currently has no standing in the property dispute.

But even if there were a way to allow Lidstone to stay, it would be an uphill battle. His home is in violation of local and state zoning and environmental regulations, and there is no access to a road.

“You guys are in a quandary. So are we,” selectman Robert Steenson said.

The woodlot Lidstone calls home is just a few miles away from Interstate 93. But it’s hidden by the trees; it’s on 73 acres that’s been used for timber harvests. The property has been owned by the same family since 1963. There are no plans at this time to develop it.

Lidstone has claimed that years ago, the owner gave his word — but nothing in writing — allowing him to live there. But in the eyes of the current owner, he’s a squatter and needs to go.

Property owner Leonard Giles, 86, of South Burlington, Vermont, didn’t even know Lidstone was there until the town administrator found out in 2015 and told him, expressing concern “with regard to the solid and septic waste disposal and the potential zoning violations created by the structure,” according to Giles’ complaint in 2016.

Giles’ lawyer, Lisa Snow Wade, said her client “hasn’t needed the stress these last few years.”

Lidstone, a bearded, small-framed, spritely man, has resisted efforts to leave since a judge issued an order for him to vacate in 2017. Following that, both sides had attempted to reach some sort of agreement for him, but were unsuccessful, according to court documents.

Currently, Lidstone can be released if one of three things happen: he agrees to leave, the cabin is demolished by Giles, or 30 days have passed since he was jailed.

“I will sit here until I rot, or I will go home,” Lidstone, who doesn’t have a lawyer, told the judge from jail on July 28 when asked if he’d agree to go back to the cabin to collect his things and depart for good.

He hasn’t had any other contact with law enforcement, unlike the case of a man in Maine called the “North Pond Hermit,” who also lived in the woods for nearly three decades and pleaded guilty in 2013 to multiple burglary and theft charges.

Over the years, Lidstone, a U.S. Air Force veteran and a father of four who has made money as a woodsman, has been known to invite kayakers and boaters into his home, sharing stories about his life in the wild.

The wooden, two-level A-frame cabin, was profiled by a local television show in 2018. There is a small, cluttered kitchen with pots hanging from the ceiling, some appliances, and curtains on the windows. His porch has a footstool with a base made of stacked beer cans. He converted a wood stove into a beehive. He’s attached lights, a mirror and a pulley for a clothesline to logs supporting the cabin. There are piles of firewood.

Nearby is a gravel path leading to vegetable garden plots outlined by logs and some berry bushes. Lidstone gets his water from a stream.

Lidstone’s decision to live in the woods is “exactly the lifestyle he wants,” said his brother, Vincent Lidstone, 77, of Lafayette, Georgia.

“What they’re doing to him isn’t right for anybody, whether he’s my brother or anybody’s brother,” he said. “He’s 81 years old. Leave him alone.”

Vincent Lidstone said he lost touch with his brother through the years, but described how the two of them and a cousin enjoyed spending time outdoors. They grew up in Wilton, Maine.

“We lived in the woods,” he said. “We camped, fishing, hunting. The three of us did everything together for a lot of years.”

It’s unclear where Lidstone would go. Vincent Lidstone said he doesn’t have the resources to help him. The Associated Press reached two of his three sons, who said they haven’t been in touch with their father recently. His daughter didn’t respond to a message seeking comment.

Gedeon said the matter hasn’t been discussed by her group yet.

“We want to see him be able to live out his remaining years where he is,” she said.
