Agrigento is in a situation very similar to the one described by @GovernorKeagan, but I’m quite satisfied with my progress during the holidays. I added basic info for most (unfortunately not all) POIs of the main street, Via Atenea, and most importantly talked to my extended family about OSM and introduced one of my cousins to StreetComplete. Hopefully she’ll keep going while I’m home. If not, we have something to do together next time I’m there!
