I founded and ran a Consulting Firm specializing in Transportation/Traffic Software.
As a result I developed a List if Distribution and Traffic Managers for every prominent USA Company.
This includes Fortune 1000 plus more.
Retired now after starting and running a very profitable Computer Consulting firm
with International clients such as Hewlett Packard, Arco Oil, Home Depot,
Target, Dupont, BaxterLabs and many others.
I believe this List will be VERY valuable for you.
