The reason we have definitions is so that we can differentiate between things. If 'rural' is a catch all that includes places like Whitwell, Pikeville, & Kennesaw, then it is a useless definition. Any child who has watched Sesame Street knows that "one of these things is not like the other." Not trying to convince this Easy123 character of anything, b/c facts contrary to his/her beliefs only seem to embolden him/her.
Just looked at the definition of suburb in Wikipedia, and it specifically mentions areas around Atlanta as suburban. Imagine that.
Kennesaw is a City of 30,000 and part of the Atlanta Metro Area. It is anything but rural, despite assertions to the contrary.
Kennesaw might have been rural long ago, but it isn't now. It's suburban. I have friends & family there, neither of whom own guns. Hate to break it to you, but that mandatory gun ownership thingy is a farce. There is no way to enforce it, and many in the community scoff at the law.
