This drove me so crazy that I had to create an account to post about it. 1620 N. Racine is not an address that exists in Chicago. That address is in the middle of a river. If you google 1620 Racine it will show you 1960 N Racine, but if you look to the south where north Ave (1600 N.) would intersect Racine it's either in the river or in a Home Depot that's been there since well before 2004. I think this further strengthens the Jacobs Ladder theory that all of this is happening in his head and he's created this fictitious address that does not exist.
