Consider the idea of not expanding the airport, and instead use all the money to build a new drag strip. A drag strip would keep Juneau's streets safe from street racers. People who are modifying out vehicles are a growing population.
Our airport is fine just the way it is. Build a drag strip, and keep the enthusiast, street racers and the public safe. The police can save some time trying to catch street racers out there. I think this would give us a safe environment and something fun to watch.
