The son and I rode Lewis and Clark Monument. Fun downhill = mega climb back up. Double black 'jump line' will launch you (I watched while Walter launched). I do recommend doing reconnaissance on the double black first, as there were bits washed out. If you are passing through the area it is a good work out. There are nice bathrooms if you want to change. Here is a link: http://trailshaveourrespect.org/trail-information/ Make sure after your ride to go to the end of the lot and check out the view.
