I live approximately 1 1/4 miles from the nearest subway (Metro) station. For years, I drove my car to the immediate neighborhood surrounding the station, parked my car on a street in that neighborhood (parking is not available at the station), walked 8 minutes to the station, jumped on the train, and, 20-25 minutes later, arrived at my office in D.C.
Last March, I purchased a bicycle to transport me to the Metro station. In July, I began commuting to my office with my bike and have continued to do so during the winter. If the temperature outside is more than 30 degrees in the morning, and absent rain or snow, I'll eagerly hop on my bike for the 7 1/2 mile, one-way, commute into the city, which takes about 30 minutes. No excuses. I'll ride to my gym, which is located near my office, lift weights for 15-20 minutes, shower, and then head off to work.
Biking is probably the only other sports activity, besides tennis (big Serena Williams fan here!), that I enjoy doing. My fondness for biking has led me to search out websites dealing with bike commuting and/or alternative transportation issues. This site will, on occasion, address both of these topics. In the meantime, though, I encourage you to check out Bikecommuters.com and Commutebybike.com if you are interested in information about bike commuting, and Streetfilms.org and Commuterpageblog.com if you are interested in alternative transportation issues. Streetfilms.org is a particularly interesting site. It is, as the name suggests, a video blog. Check out the Streetfilms.org video titled "Portland (Green) Bike Box!" It's great stuff!
