Here's what we do in late Fall when facilities are closed: the regular take out campground, just east of the Rouge river, on the North side of rd 148, has a very wide gate. We park outside of the gate, along the metal fence, so as not to block the left part of the gate. If that's not a possibility, park on rd 148. Finally, if that's not an option either, do what many have done: the shuttle isn't very long--hide a bicycle near the take out... It might be possible to use the camp ground on the South side of rd 148, a bit further East, but it costs $. Good luck! --C.
