One of my fave local technical trails for mountain biking: Sawmill in Soderberg Open Space
Sawmill is awesome. Not a long trail, mind you, but rugged and fun. When you start at the Stout Connector, go up Stout, down Sawmill, and back to the Soderberg TH via Nomad and Stout Connector again, it's just a blast. This is the techiest part.
