Eric is right, it is on the bailout option connecting towards Kickapoo exit. However, it is two BIG downed trees side-by-side. If you look at the trail map, it is after the word 'Mound' (of Blue Mound), but the trees would be just at the start of the blue trail line... just before the descent on the actual trail.

I rode Blue Mound Monday night and had to hop the first tree, then walk one or two steps and hop the next one; lifting the bike over each.

I'm leaving town Wednesday and will not be back until August 7th or 8th. I can help with Sunderbruch at that time. Whether it's these downed trees, more downed trees, or just plain 'ol weed whackin'!!!
