AMR has been in Natchez for many years. They even have had a VHF system for coverage in the area since well on 30 plus years. Though Metro Rural was primary for much of the area, and some coverage from that other service out of Louisiana... Med Express. Pafford is the big dog there now, with AMR on rocky ground lately. AAA wanted to expand over from its McComb base, but that never gained traction. They did manage to get a secondary footing in Lincoln County though KDMC is primary EMS there. AMR got Jefferson after the complete bailout of an EMS service that resulted in a state law regarding EMS agencies being able to operate... $$$ lost big time makes Legislation happen.
