As Donna has said, these town events are organized locally by the small towns and they never think to put any info online, mostly because they think only of locals being interested in them; if they ever do it at all, it is last minute like a week before. The most common method used here for promoting local events are POSTERS around town. That's a very handy thing to know -- once you're here, keep a lookout for posters and you'll see food festivals or other events for the time you are here, most often held on weekends. That way instead of eating at restaurant one evening, you might choose to go to a local sagra or other festival where you can enjoy local specialties with other locals.
