The Longemont address is correct for 1968 but not for 1972 W lived elsewhere.
two other memos are at USA Today site along with the 4 preciously posted at CBS:

Did not wish to make a statement that the Adress was correct for the time the memo supposedly was written - instead wished to confirm that it was indeed a valid adress and that GWB had lived there. The other link also only serves to verify that the PO Box number, although "funny", was indeed valid for the unit.
All of which only means that the forger was clever enough to do "some" basic research to get a few details "correct".
