Read this: Many communities have small air taxi services. These operations originated from the demand for customized transport to remote areas. Perhaps the most quintessentially Alaskan plane is the bush seaplane. The world's busiest seaplane base is Lake Hood, located next to Ted Stevens Anchorage International Airport, where flights bound for remote villages without an airstrip carry passengers, cargo, and many items from stores and warehouse clubs. In 2006 Alaska had the highest number of pilots per capita of any U.S. state.
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): Lake Hood is located next to what International Airport?
Ted Stevens Anchorage International Airport
