Some happy bike commuters from the 2008 Bike to Work Day

On Thursday, May 14th, expect a jump in the number of bikes on the road in San Francisco. The reason for the inflation? Bike to Work Day. This will be the 15th Annual Bike to Work Day in San Francisco and the surrounding Bay Area, and this year nine Bay Area counties will participate in the festivities. The event seeks to promote a healthy way of commuting by featuring commute convoys, energizer stations, prizes for costumes and decorated bikes and downtown bike valet parking. Many organizations like the California Academy of Sciences have put together bike-commute teams to support the event.

The Bay Area is not the only city promoting bicycle advocacy. The best known community bike program was started in the 1960s in Amsterdam. Known as a bicycle sharing system, bicycles were available on a large scale, allowing people to have ready access to these public bikes rather than owning personal ones. This allowed people to shift from transit to bicycle and back again. These programs have not only been successful in Europe but the United States as well.

One of the first community bicycle projects in the United States started in Portland, Oregon in 1994 by several civic and environmental activists. A number of bicycles were available on the streets for use. Since then many other communities have set up similar projects. One was set up at Burning Man in 2007, following the example of the Portland Yellow Bike program.

150,000 commuters are expected to forgo their car commute and bike into work on May 14th. Nationally, many more will commute by bike during the entire month of May to support National Bike Month.

There are some great perks to commuting by bike to work: Bikes are much cheaper than cars. Typically, a bike will cost around $700 per year; compare that to the cost of a car (which includes insurance, repairs and gas), around $8000 per year (according to the American Automobile Association). Not only is it cheaper, the carbon footprint of commuting by bike is drastically lower as well. A gallon of gas releases about 20 lbs of CO2 into the air; a bicycle creates no CO2 emissions. Bicycling is also a great way to stay healthy and active without having to make a trip to the gym.

All in all, Bike to Work Day is an individually and environmentally healthy way to get to and from work. For more information on Bike to Work Day, bike routes, and services offered for bicyclists visit http://btwd.bayareabikes.org/.

Cycling and photography are two passions of mine that I ardently pursue in my free time, so it was only natural that I felt an immediate kinship with Your Photo on QUEST's featured photographer Randy Davis. Randy explores remote locales in the Bay Area on his mountain bike, which allows him to access places that are tougher to reach by car or on foot. He's often accompanied by his dog Lucky, a Saluki mix whom he rescued from the streets; this requires some skillful maneuvering at times as he has to manage Lucky's leash and his heavy camera gear. We conducted our interview and took photos in the Castle Rock Recreation Area of Mt. Diablo State Park, with the help of fellow cycling enthusiast and sound person Bill Stefanacci. We wished that all of our work days could be outdoors in the sunshine and on the bike!

Randy has donated prints to Save Mount Diablo, an organization dedicated to preserving the land. They're also partners with the Mountain Diablo Interpretive Association, a "non-profit volunteer organization which assists the California Department of Parks and Recreation in maintaining and interpreting Mt. Diablo State Park for its 700,000 visitors each year."

Randy's currently working on a new series focusing on the bald eagles in the Bay Area. You can also see more of his work on his website.

And with gas prices rising, parking a headache, and a desire to reduce their carbon footprint, more and more San Franciscans are cycling in the city to work and to do errands. Cycling rose 15% between 2006 and 2007, and injuries from bicycle collisions are down over a 10-year period, according to municipal studies. But the city's been spinning its wheels to increase bike lanes because a 2006 injunction has barred their installation. And it's still an uphill climb, even here where environmental consciousness is high, to convince people to cut their car use.

Quest follows a recent convert as they negotiate the treacherous streets of S.F., guided by a member of the city's bicycle coalition. We add up the gas and carbon emissions they are saving and find out what has prevented would-be riders from commuting on bike. lastly, we talk with city traffic managers and find out what the most bike-friendly cities are doing.
