No free books at Walden Pond

Rich writes Boston Globe has a story about a Henry Thoreau reader who tried to teach people how to download free copies of Thoreau’s Walden, but was
prevented by a state park ranger.
“But Eldred had barely driven his white-and-red camper into the parking lot of the Walden Pond Reservation and tacked up a handwritten sign reading “Free Walden” when a state park ranger asked him to leave. Eldred said he was told he needed a permit to hand out copies of the book, free or not, and would be arrested if he continued””
