If you've seen this guy out on trails, his name is Dax and he's not a security robot - he measures sidewalks and outdoor features for Missoula County's ADA self-evaluation. The county said up front that his cameras point at the pavement, not at people, and no personal data is collected. 651 reactions, 207 comments, 212 shares. Why it works: naming the robot and answering the surveillance question before anyone asked it turned a compliance survey into the week's most charming tech post

Denville Township announced the first 17 acres of the historic St. Francis property are officially acquired, the opening step in permanently preserving nearly 50 acres - 'a once-in-a-generation achievement,' in Mayor Tom Andes's words.

Why it works: a land deal announced in phases, with the acreage and the next closing date stated plainly, reads as stewardship rather than press release

Gloucester County's mobile trailer offers free showers, laundry, and basic necessities - 'Everyone is welcome - no cost and no judgment.'
