Here is a description of the daily commute by Michael Milken, 1980s junk bond king, as told in "Predator's Ball" by Connie Bruck:

At 5:30am each weekday in the early 1970s, a bus pulled up to a stop in Cherry Hill, New Jersey, and a young man lugging a bag that bulged with papers mounted its steps. He was making the two-hour commute to New York City, where he worked at the investment­ banking firm of Drexel Firestone. The train would have provided a more comfortable and faster ride; but, for those very reasons, it also offered more opportunity to meet other Wall Street acquaintances. They would want to engage in the kind of idle small talk that commuters share to pass the time. The thought must have been intolerable. He did not wish to be rude, but he wanted no interrup­tion.

As soon as he had settled into his seat, being sure to take one with an empty one adjacent, he unloaded a mountain of prospectuses and 10ks (annual Securities and Exchange Commission filings) onto the seat next to him. On winter mornings the sky was still pitch black and the light on the bus was too dim for him to be able to read. He wore a leather aviation cap with the earflaps down; he had been bald for years, and although he wore a toupee his head always felt cold on these frosty mornings. Now over his aviation cap he fitted a miner's headlamp -- strapped around the back of his head, with a huge light projecting from his forehead.
