Did the Chicago mob ever do business with New York, and has there been any business done in the last 10-15 years between the two? For example has a boss from New York ever came into Chicago for a meeting or has a Chicago boss ever taken a trip out East to meet with the Commission or a boss out there? Do Chicago and New York mobsters even like eachother?

Anyone here who can provide input on this it would be much appreciated. Thank you.
