Some place details from Overture Maps (CDLA-Permissive-2.0), checked against the Census town line. Places added by neighbors go live once a second neighbor confirms them. Spot a mistake? Open the place and tap Edit mode.
How we sort and count
Each list puts neighbor favorites first (ratings and photos), then the most complete listings (a website, a phone number, a note), with local, independent spots ahead of national chains. Categories come from each place’s map category, so a café filed under “Shops” still shows up with the cafés. “A five-minute walk” is a quarter mile from the busiest spot on the map. Per-1,000 figures use the Census population.
