If you live in Minneapolis I need a favor. Can you check the phone directory for a Donald J. Zimmerman who lives on Elliot Avenue. I need his house or apartment number and the phone number if it's listed.
I suspect he may be the same man we called "Zip" and served in the USAF together in Vietnam in '67-'68. He was from Iowa originally and I have been searching for him for over 35 years.
