Hi elementbryon, thanks for the offer! Where I live, we don't really have any "bike specific" trails, since I live on a reservation, but we do have a lot of old logging roads that are great for mountain biking. Nearby, though, just outside Grand Marais there are some pretty popular trails, including some singletrack. They have also been working on some trials-type trails on Pincushion Mountain, just outside of Grand Marais. In Lutsen, the Lutsen Mountains ski area also has lots of biking trails, including some downhills.... you can actually ride some of the lifts to the top of the mountain and take your bike down. I've never done this, but I've heard that its quite popular.
