Excerpt:
Perched along Interstate 96 near Milford Road for the past month, a large red billboard asks travelers in the thousands of vehicles that pass it daily: "What is Islam? Who are the Muslims?"
The sign in Oakland County also lists a phone number and website for GainPeace, a Chicago nonprofit associated with the Islamic Circle of North America.
The curious who follow through have the chance to earn a free copy of the Quran, the Muslim holy book, and learn more about the religion, which is the aim of the group's campaign.
