In more recent times with improved transportation, centralized and much larger elevators serve many farms. Some of them are quite large. Two elevators in Kansas (one in Hutchinson and one in Wichita) are half a mile long. The loss of the grain elevators from small towns is often considered a great change in their identity, and efforts to preserve them as heritage structures are made. At the same time, many larger grain farms have their own grain-handling facilities for storage and loading onto trucks.
