While I don't like writing places like the ATF (which now belongs to the Department Of Justice) I had to get it straight from the horses mouth. I posed the question of concealed carry, school zones and reciprocity (using Georgia and Florida as examples). Read the entire response but pay particular attention to what I placed in bold. I take this response to mean that along as you obey the state law the ATF won't get involved. Of course there will be some who will argue this to the death. I will continue to carry as I have.:
Thank you for your inquiry to the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF). Generally, it is unlawful for any individual to knowingly possess a firearm within a school zone. A school zone is defined as being within a distance of 1,000 feet from the grounds of a public, parochial, or private school. This prohibition does not apply to the possession of a firearm on private property not part of school grounds, such as an FFL's business premise (e.g., commercial storefront, residence, or driveway).
Once a customer leaves private property located within 1,000 feet of a school with a firearm, they may be in violation of Federal law.
However, in the following situations an individual would not be possessing a firearm in violation of 922(q)(A):
1. The individual is licensed by the State or political subdivision
to possess the firearm, and the license was issued after law enforcement officials verified that the individual is qualified to receive the license;
2. The firearm is unloaded and is contained within a locked
container or a locked firearms rack that is on a motor vehicle;
3. The firearm is possessed by an individual for use in a
school-approved program;
4. The individual or his/her employer is doing so in accordance
with a contract entered into between the individual and the school;
5. The individual is a law enforcement officer acting in their
official capacity; or
6. The individual is crossing school grounds to reach a public or
private way. Their firearm is unloaded, and they have permission from the school.
ATF realizes that not all persons who enter or exit an FFL's premises in such case may fall under one of the above-described statutory exemptions. Therefore, ATF advises that in those States where a permit is not needed, the FFL should ensure that a purchaser's firearm is unloaded and placed in a locked container prior to leaving the business premise.
In addition, You stated that you have a Georgia State License, ATF does not have any jurisdiction over the State of Georgia, Florida or any other state.
