There are two traps located on this hilly portion of Ygancio Valley. The first, headed toward Clayton is usually 2 or 3 motorcycle officers hidden behind brush on the side of the road. Not one person goes the limit of 55mph, so they pick out any one person to ticket. The second is in the other direction headed toward Walnut Creek. Usually a cruiser pulls backward into an empty gravel driveway which is located over a creek. They then proceed to use radar on everyone coming down the hill. It is posted 45 at the bottom of a huge hill and there is no apperant reason for the decrease of mph. Watch out on this stretch of Ygancio, there is usually at least one police officer on on side of the road or the other!
