CID shows Chicago IL - I have not been able to identify who this (or who they claim to be) is yet.  The scam of the month for August is industrial roofing and I suspect this is related as we've received many other "Chicago" calls regarding industrial roofing for some reason (we're not looking for roofing and no one in their right mind would employ a roofer unsolicited as a result of a cold sales call but the scam of the month doesn't have to make sense).  This one has called at least every other day for the last week but I can not get any information out of them yet.
