While the zoo and airport and not far apart, they cannot be considered the same neighborhood, particularly if you re talking about walking. They are about 3 miles apart, but perhaps more importantly separated by two major interstates - I-65 and the Watterson (I-264) - and a third local one, Preston Highway.The area around the zoo, while not the best part of town, is not the worst either. Residential, generally pretty livable.The area immediately around the airport, as the case with many airports, is pretty rough.
the first answer is right- the zoo and airport are not in walking range. the neighborhood around the zoo is pretty decent- there s a few parks in the area, a hospital, schools in the area, not too bad as far as crime goes.
