1. I would like the 
-name
-title 
-location (ie. street address and city), and 
-phone number (not the general 1-800 number for the company) of the
Hub/Terminal/Station General Managers (or equivalent title) for Fedex
Ground and UPS in the following Michigan cities:
-Detroit
-Saginaw
-Lansing
-Flint
-Grand Rapids.

I am not sure if each city has a Hub, or if only Detroit does. I also
suspect Detroit may possibly have more than one Hub. I believe the
words Terminal and Station may be used interchangeably, and that I am
asking for two levels of management: Hub being more senior, Terminal
or Station being one level below.

I am not interested in the locations where consumers and businesses go
to drop off packages; I am interested in the facilities
(Hubs/Terminals/Stations) where packages are processed before they are
shipped around the country and world.

It would also be very important to know any sources used to get this information. 

Thank you for your consideration.
