They are available at the Columbus International Airport.

On foot
Navigating the NW portion of Columbus by foot would be a bit difficult for the average person due to the size of the area. It is more easily traveled by bus, car, taxi or even bicycle.
By car
The area between I-71 and I-270 outerbelt has numerous exits into this area. The roads are well maintained and traffic is acceptable, other than during rush hour when people are going to and leaving work. If you are not familiar with the area, you may want to sit it out during that period. There are plenty of diversions.
