Was riding last weekend at spearhead in St paul went exploring some old trails where we used to ride a while back (before the power plant). Anyways went past what we used to call the slate dump or the playground which is now a conservation area...anyways went on by and down the hill came to some trail markers marked 101 and on each side of that were "do not enter". Soooo I turned around and just kept riding the other trails well I ran into a guy on a diamond plated side by side and we got to talk in and I asked him about it and he said u had to buy another permit to ride those trails and he sold em and they would be $10 a piece BUT if I hadn't already bought a spearhead permit he could sell me one for $50!for both systems???. Anybody know anything about this?
