One issue here: DESCRIBE is implementation specific.
So while most endpoints will deliver all ?p ?o triples with ?town as a subject (even ?s ?p and ?town as object), you cannot be sure that all services will return the same thing.
However, in Olivier's case, I guess you're working with a single implementation so that may be ok.
