My wife wants to know the meaning of the site name. Do you mean the first four graduating classes? School opened in '64 so she's confused and will make my life a living hell unless I get an answer.

My answer is:

Yes - I meant the first four years that classes left Gateway as graduating seniors - I know that at least one set of students left Gateway in the spring of 1965 - going off to Woodbury for most districts - Wenonah students somehow had a choice of Woodbury or Pitman. Those students left (I think) having only completed the ninth grade at Gateway.
