Sure. The short answer is we are. The longer answer is that we reviewed an electronic automatic fare collection system about 10 years ago. You're quite correct. We have a very old-fashioned gravity system. It's simple; it works. It's certainly not as convenient for the customer as the types of systems you're referring to. There's no business case. There's no system in the world we know of that has made a business case to actually transfer its current fare collection system to an electronic fare collection system.
So 10 years ago when we did that work, we said we can't afford it, it's going to cost us too much money, it's going to cost us more, and we're not prepared to go there.
