More than a quarter of the Bay Area’s workers are employed in Silicon Valley. The local work force and communities are certainly what could be called above-average when it comes to tech savvy!

We have so much beautiful weather in Santa Clara County. In my free time, I really enjoy bicycling on the combination of flat, hilly, and mountainous terrains. You can certainly get your exercise by trying out some of the local rides, or joining one of the local bicycle clubs. Many interesting bike routes begin in Santa Clara County, and the region has excellent bike lanes. As a hiker, I also appreciate the numerous nature trails that take me to scenic destinations, but are only moments from civilization.
