This is a wonderful idea. I had the exact same idea on my first trip to the Metro during my sophomore year of college. That is probably a mistake I made thinking about myself.
The idea is to offer continuing education classes as a way of continuing to expand your knowledge and understanding of the city you live in. Metro is currently the third-largest transit system in the US and it continues to evolve and grow. They also have two really unique things going on right now. One, they’re adding their own subway cars, which for the most part are made by themselves, and two, they’re getting into the electric bus business.
