To the best of my knowledge, although he gave out that address he didn't actually live there. Go to this address
http://www.homes.com/Home-Prices/MO/KANSAS-CITY/ and put in the address 3620 N LISTER AVE KANSAS CITY, MO. If you look at this map, the house indicated is the Irwin home. Proceed up N. Lister to 3718. I count 5 houses between them, on the same side of the street. This address is certainly not far way from the Irwin home--I would say it is within eyesight. There is an intervening cross street, NE 37th street.
