Plano has 3 senior high schools: Plano West; Plano Senior; and Plano East.
He attended Plano Senior.
That school gets fed from both middle class and poor areas.
It gets confusing; technically east and west are known as Plano East Senior High and Plano West Senior High ... this does not resolve the question why he was attending a HS in Plano when ostensibly he lived in Allen.
