The South is a stronghold for Jehovah's Witnesses in the US. The traditional religious and political conservatism, rural demographics and 'southern hospitality' makes for an easy transition for the locals to become Witnesses. In fact, many continue with the same intensity they had in the religious upbringings as Witnesses - it's all in and fire and brimstone (the threat of shunning and Armageddon).
Those of us who are from the south know that it's the 'group mentality' that prevails. Individualism is frowned upon. It's a "my granddaddy thought that way and my daddy thinks that way so I'll think that way" mind set that is deeply intrenched in southern culture.
The south is also thriving economically (has been for the past 30 years) so this makes the southern US very appealing to the Watchtower leadership (sorry Honesty....).
