there are some overgrown dh trails at Searchmont. I was one of a few who built them quite a few years ago. No races there in at least 10 years. For 2 years their was a dual ontario cup/ michigan cup there. the dual cross course was great. You may be able to contact them this spring but liability seems to be the issue out there in the warmer months. There aren't enough ppl that ride dh here to make it feasible. There are a lot of people that ride but dh is pretty limiting depending on the terrain you have near you. the trails at searchmont aren't for intermediate riders either, someone could get hurt very easily out there. Do you only ride dh? There are a lot of other options for riding here and we are adding more singletrack all the time.
I not a DHer but i'm looking to try it. Even try competive if its available. I've heard of the single track over at hiawatha but have no idea were they are in the park. I run Xcountry there and not once have I seen single track trails? Uneless its all around the big sand hill. Do you have a map to show were.
Not much for dh riding, but the xc is fantastic and very aggressive, think buckwallow on steroids. There is not much info on the net but try and conect with some locals, no we don't have a club, but there is a group ride from the outside store (522-1755) on wednesday night. Also drop me a pm and I am more than willing to show you some trails.
