The challenge can be figuring out which bus you need. Take a look here; pick a route at random. Don't forget that there are local bus systems, as well, which overlap in places, and may or may not transfer fares to the Metro. I used the public transit system to get to work several years back. My daily commute involved a local bus (after getting a lift to that stop), the subway, and Metrobus. Time? About an hour and a half or so. Travel time to drive myself? About 30 minutes. Which is another issue about the public transit system... You're on their schedule. Which can be a problem as more people are working more erratic hours -- and there's the whole issue of emergency trips home or mid-day errands.Step 1. Get on the bus at your point of departure
Step 2. Pay for the service you are about to recieve
Step 3. Sit on the bus as it travels from that point to your destination
Step 4. Get off the bus once it reaches your target destination
Its complicated I know, but im sure with the right support and training he will eventually come to the level of mastery required to Take the Bus.
