'somewhere just across the hudson' is the definition.
I can't tell whether this defines the answer.

'old nyc inuit moving' is the wordplay.
'old' becomes 'o' (common abbreviation eg in OE for Old English).
'moving' indicates anagramming the letters (letters are moved around).
'o'+'nyc'+'inuit'='onycinuit'
'onycinuit' is an anagram of 'UNION CITY'.
