if you mean pine lake (as opposed to pine coulee) haven't tested it yet, just got here a couple hours ago, but i can tell you that, last week, it was good enough to walk on and take a quad or sled around the perimeter ... but i wouldn't drive on it. my opinion, up to you.
if you choose to drive on the lake, please open windows, leave seatbelts off and leave the kids with me
