Safe to assume that you can park wherever you can find a spot near the expo/start. The expo is at the Ford Community & Performing Arts center at 15801 Michigan Ave, Dearborn. The start is about 2.5 miles west of there, just north of Michigan Avenue off Monroe (Monroe is just west of Brady).
Please remember that the Expo is only on Friday April 12 from 3pm - 8pm. If you are picking up your packets on Saturday morning, that packet pickup is at the RACE START! We recommend you come on Friday and avoid the race morning crush!
