I for one cannot protest the recent M.T.A. fare hike and the accompanying promises that this would in no way improve service. For the transit system, as it now operates, has hidden advantages that can't be measured in monetary terms. Personally, I feel that it is well worth 75 cents or even $1 to have that unimpeachable excuse whenever I am late to anything: "I came by subway." Those four words have such magic in them that if Godot should someday show up and mumble them, any audience would instantly understand his long delay.
