Bonjour Rick! I live in San Diego, California, but we visit the south of France 3 times a year. We have a tiny apartment in Mougins-le-Haut, about 30 kilometers from Vence. We have a French friend who knows a local beekeeper in Grasse, but he uses traditional hives and only speaks French 
. I have heard from him that it is a nice area for beekeeping. The main issue he has is attacks on the hives from Asian hornets (frelons).
You might ask your question in the Le Coin des Francais thread too. There are a lot of French Flow hives, but I don’t recall reading of any near you in the Alpes-Maritimes.
