The fine old hotel where Wales have set up their Chicago base probably hasn't seen quite so much muscle march down its corridors since the days when mobster Al Capone's henchmen called the city home.When Wales move in these days they unpack a culture geared up to constantly look for ways of improving the players and their performances.
Nothing is left to chance as match facts are analysed, monitored and preparation is fine tuned. It is an environment geared up to constantly seek for improvements as the coaches demand excellence and commitment at every level.
One man who has seen this system blossom and grow is in no doubt that Wales boasts some of the finest back up staff in world rugby.
The Welsh Rugby Union President, Dennis Gethin, may by an acquaintance of Prince's and Prime Ministers as an ambassador of rugby in Wales but he is fiercely proud of his association with the players themselves.
Dennis never misses a chance to chat to the players and is a keen observer of the professionalism they adhere to and rely on from the backroom team.
He said: "The intensity of the work which goes into preparing these players for international rugby is incredible. The players are monitored hour by hour, not just day by day or week by week and you get the impression that everything is geared up to look for ways to get better and better.
"I am glad to say that an environment like this also seems to attract extremely nice and honourable people who it is a pleasure to work alongside.
"My role with the squad is to foster relationships with the host unions but that means I get to see the team working and operating in their elite environment.
"It is a dawn to beyond dusk operation and I am full of admiration for the precision and focus that is achieved.
"It is a highly organised environment but I am glad to say that it not only attracts determined and skilled players and off the field staff but they also happen to be very nice people who love what they are doing and it shows."
The level of organisation at work means a player like Luke Charteris can be flown across the Atlantic at short notice and immediately feel at home in a regime within which he knows what to expect and what is expected of him.
Players like John Yapp also thrive on the challenges placed on their talents by the coaches who want him to discover just how good he can become as a tight head prop.
John relishes his task saying: "I have been playing for quite a few years and it is great to have a new challenge which means I have to learn new skills. I am getting a tremendous amount of help and now I just want to give it a go to the very best of my ability."
Today storm clouds gathered over Chicago with strong winds, torrential rain, thunder and lightning.
Whether that symbolises the energy about to be unleashed by Wales in eighty minutes of international rugby will be known on Saturday.
