This from Drew Smith:

It was stated recently by firefighters from both Itasca and Wood Dale that both will soon be dispatched by DuComm with Wood Dale using new rig numbers of 68 and 69 and Itasca using 60-something.

I have confirmed that effective 5/31 at 0900 Itasca will switch to DuComm.  Itasca’s apparatus will use “66” for front-line units and “67” for reserve units.

Wood Dale is also switching to DuComm and will use 68 and 69 for their stations. Date of their switch is not confirmed.
