The "Moffett Bay Trail" is 97% representative of all the trails throughout the Bay Area. [The remaining 3% are the yet-to-be-improved (AWS) or connected/segregated trails.] I have thoroughly enjoyed the segregated status of a well-maintained/relatively smooth/wide gravel track just above sea level. It is SO NICE to not be on busy city streets, though sometimes there can be a bit of congestion with other trail users. And the weather is pretty darn nice--I compare it very favorably to the slightly superior "International Ft. Hancock - Las Cruces I-10 Bicycle Bypass" (in the not-quite-a-mile/~1.6 kms high "¡Hidden Gem of the World, Crossroads of North America, anchored by El Paso, Cd. Juárez y Las Cruces!"); the former in the rain shadow of the Santa Cruz Mountains, the latter in the Northern Chihuahua Desert. I highly recommend it for a long level route, connecting Stevens Creek Trail/Mountain View with Caribbean Drive/Sunnyvale. I've cycled it in both directions, and actually saw an unmarked dirigible overhead, sailing around Southbay, practicing navigation/maneuvers before landing back in the super-secret Lockheed-Martin/Moffett base/Google complex.
¡So interesting, and definitely has my coveted "iWheel of Approval!" read more
