... you can get a nice picture of the area if you go to maps.google.com and enter the address, "4415 E. Cotton Center Blvd Phoenix AZ". To the right of the arrow, you can see the traffic circle and the driveway headed south to another building ... which I presume is where ADTRON is. I worked a temp job in the bigger building to the north for several weeks in 2002. Nice area.
