Robb Clark asked a good question

How did Oswald get to work at the TSBD from the day he was hired until the day before the assassination? If he was taking the bus where is that bus driver? What bus route was this? Where are the other passengers on this bus route.  If Oswald was taking the bus everyday early in the morning all the other people on the bus would be going to work too.  Where the heck are they? Why is there, to this day, a very large hole, like this story crying out for attention?

Why were we limited to the dufus Cecil McWatters?
