Hey New Pictures!! Yet another MTBR adventure. The Ogre hooked up with Steve and some others and we rode South Yuba trail up North of Nevada City. South Yuba Pictures and Mini Ride Report. South Yuba is an awesome Lower Sierra Nevada mountain bike trail, the views are awesome and the trail is oh so sweet. This is an excellent winter ride because it is almost always snow free and rideable. If you like cross country riding this is a choice trail.
