Yes, but Ochlocknee and Calvary are both 'suburbs' of Cairo, although I don't recall if Ochlocknee is in Grady county or just across the line. I'd guess Ochlocknee and Calvary to be about 20 miles apart.
I know Cairo and Calvary and Havana...heck, I even know Climax and Attapulgus - but I must say I've never heard of Ochlocknee. Is it on the river?
