As our eyes age, they have a tougher and tougher time adjusting to rapid changes in lighting, and we need to be aware of this.

Metro, built in the late 20th century, is the most escalator-dependent system in the world.

Metro shows no signs of being able to make its trains run on time. This occurs during single-tracking and it occurs during normal rush hour service.

I think that maps showing platform details would be useful to visitors, especially to chaperones of school groups, etc. Also useful would be either a compass rose or an arrow pointing North at every metro exit. Emerging from underground is disorienting, especially at night.

I don't like the midnight closing on weekends. It's one thing to tell people they have to drive to Jiffy Lube Live in the outer suburbs.

Many Saturday mornings, I take 495 from Fairfax to Maryland in the morning, and I'm astonished by the speed of many of the drivers. Even when I drive 70 mph, I'm being passed by people driving 80-90+ at times.

If you think your job requires you to endanger people, get another job.
