Join the Chain Gang on less-used but interesting roads from Cotati Vets to Petaluma including Poplar, Eucalyptus, Middle Two Rock, Spring Hill, San Antonio and I St Extension.  Some roads have quite rough surfaces and I St Extension even has potholes - so be warned.  After a break at the River Front Cafe at 224 B St, Petaluma, the route returns to Cotati using the SMART trail.
