Phil Shaltz, owner of Shaltz Automation in Flint, is the man behind the mysterious "blueberries" billboard on I-69 in Flint.

Flint area entrepreneur, business man, and  philanthropist, Phil Shaltz, sets out to better the world with a rather simple pay it forward concept "I'm concerned about the Blueberries."  Getting national attention with this strange phrase since it has nothing to do with actual blueberries and everything to do with helping fellow human beings.
