It depends on where you're at and what you like to do. There are several Jeep clubs in the state where you can hook up for trail rides. Some are private parks, other areas like Yankee Springs (Allegan), the Dunes at Silver Lake, West Branch or Drummond Island range from ORV routes to seasonal roads (that get very interesting in the spring and winter). Besides the Jeep-only clubs, there are the long established 4WD clubs in the state. Might want to start by checking in with the Great Lakes Four Wheel Drive Association. The GLFWDA isn't a club per se, but they can help you out, too.
