In Tongyeong, I was barely .5 mile to school, and public transport there was so modern and ubiquitous that I never needed a car, even when traveling across the country. Key West is an island only about 4 miles long, so round trip to the grocery store (my longest venture) was 3.4 miles; a "long" bike ride (or motorcycle trip). I loved not being part of the pollution problem, too! Enjoying the fresh air, experiencing the fun of walking and riding my bike, all part of the being outdoors. You are really involved in life when you are not caged in a vehicle, and you can notice so much.
I'm walking to work tomorrow, and I am looking forward to it! (Still got to get the bike fixed!) I am so grateful I get to walk to work, and that I work at a place that encourages a pedestrian lifestyle!
