Okay, some assumptions to establish before discussing a zombie apocalypse. The most likely cause would be a weird rabies mutation, so you have brutal creatures that seek food, in the form of flesh, and will accomplish this desire with no regard for their own body and spreading of the virus is accidental and requires bodily fluid contact.  The horde will resemble something closer to 28 Days Later than Night of the Living Dead. Combating these creatures requires fatalities but no arbitrary head injuries or supernatural elements. The virus would arise in a developing country and spread rapidly, destroying governments and leaving wide swaths of continents of Africa or South America inhabitable to the general public. A drained government organization, think CDC,  that's attempting to deal with infected American doctors of both Ebola and the zombie virus allows it to spread within it's facilities and after a few days of an attempted military quarantine of a major eastern seaboard urban centre, the virus begins to spread west. This means that the general population of Lexington would have considerable time to become aware of the virus, and even a week or more before infection within the continental United States becomes common. Some semblance of infrastructure would still exist along with heavy military action, and a complete destruction of the current structure remains unlikely or at least would take considerable amount of time. That's not to say it's likely to survive. In the panic emerging from the news of the spreading virus, grocery stores are raided, local police forces are overwhelmed and general anarchy emerges. cross country travel is prohibited either by crowded highways or military forces attempt to control the outbreak by indiscriminate shooting. The high number of guns in American homes and paranoia of their owners means it's just as likely to be shot by a fellow survivor then eaten by a zombie. My best bet would be to remain inside for about a week once the virus hits Lexington until the initial chaos subsides. I live in a wealthy enough neighboorhood that a large portion of the inhabitants would be able to abandon their dwellings at the beginning and head for another place, reducing the population of potential infected and dangerous survivors/ The number of my neighbors that would immediately turn to gun violence means that traveling outside would be dangerous, and the large quantities of zombies that might inhabit my surroundings would be far more attracted to the sounds of gunfire. The security of my basement, the quantity of food in my house, and the number of effective blunt weapons and my physical fitness means I have a good chance of that short term survival. Once that most initial dangerous period subsided I would attempt to make my way to a friends rural house in a less inhabited area and would have weapons more effective for home defense like guns.  If there was a complete institutional failure or I was required to take care of my friends or family I would most likely perish rather then forsake human dignity.
