Please answer a question about the following article about Dutch language:

Some Flemish dialects are so distinct that they might be considered as separate language variants, although the strong significance of language in Belgian politics would prevent the government from classifying them as such. West Flemish in particular has sometimes been considered a distinct variety. Dialect borders of these dialects do not correspond to present political boundaries, but reflect older, medieval divisions. The Brabantian dialect group, for instance, also extends to much of the south of the Netherlands, and so does Limburgish. West Flemish is also spoken in Zeelandic Flanders (part of the Dutch province of Zeeland), and by older people in French Flanders (a small area that borders Belgium).

What area that abuts Belgium still has some older people who speak West Flemish?
French Flanders
