Here's the thing, there are spots that people wheel with permission around southern ontario, often people will not give that information out on the internet because you get all the jackasses that come out and destroy property, wildlife, they litter and have loud trucks that ruin it for everyone else. So it's highly unlikely to have spots revealed to you on a public forum. If you want expedition type trails or rocks you have to make a weekend out of it. I've run minden trails over a weekend and I'm assuming the kind of rig your running is probably not capable of those trails anyway. You can buy and download a trail map for minden trails, we run the 3 and 4+ trails that require lockers and a winch but there are a few lighter trails but you have to drive 2 or 3 hours to run them.
