If you're not familiar with OCM you are missing out. They are an awesome resource for mom's in Metro Detroit. Their site includes event listings, product reviews and more.
On a side note: High recommendations for the Detroit Riverwalk. Our family spent the afternoon there yesterday and it was beautiful. Carousel Rides for $1.00. A really nice cafe with snacks and ice cream. Bring your kid's suits, the fountains in front (or behind) of the Renaissance Center are amazing.
