The one thing about reer nugaaleed, we are very veryyyyyyyyyyy anti aboriginal clans in Somalia attacking any darod region. It must be a nugaal thing niyahow. Bari ain't like that. Mudug is though. That's why I say mudug/nugaal were really one before the border crap, the culture identical, my father you can't tell if he is reer nugaal or reer mudug, he speaks and thinks the same. But I have noticed reer bari/sanaag are very different, I mean the ones near the coastal lines.
But from say garacad-galkayo all the way up to karkaar(qardho, isku shuban, etc) into hayland into sool and nugaal, it's exactly the same culture, dialects, mode of living, etc. It should be really one state niyahowwww not the way it was carved up by previous somalia govt administration.
