Do local hashtags still work?

Yes, a few, with the neighbourhood and the kind of place, on the piece that asks for a visit. A long list of generic tags does not bring the neighbour and clutters the caption. Note what people in the neighbourhood call the area, not the nickname an account from another city uses. Thirty food tags bury the hours, and the person searching the neighbourhood never sees them. Each visit piece carries three tags at most: neighbourhood, kind of place, and city.
