For the first time in several months, I rode a bike today. Not for fun, but for transportation faster than my legs. I thought about how wonderful bikes are as a mode of transportation when you’re not traveling far distances.

“I want to live in a community that localizes most of the facets of my life,” I thought.

Then, I saw this video and that desire intensified. Only 90 seconds with no words, it illustrates the importance of a number most of us don’t know the significance of.
