Roger Penske's has been mentioned in the same breath as other civic leaders and with good reason; he helped bring the Superbowl and is involved with M1. However, why has he not committed his own firm to downtown? Why is Penske Corporation still located in Bloomfield Hills if he's a big advocate of the city? I am not sure how many people actually work at Penske's HQ, but it would still be a nice addition to the cityscape.
