Riding bikes yesterday with my friend Rob from Juneau, I asked if he cycled to work. "I walk," he said. It's only 3/4 of a mile from his condo to the office. Then he said his daily discipline is to pick up one piece of trash each way. He said you'd think there would be days when he wouldn't find any, but so far, that's never happened. "But you know," he said. "It got me thinking. Who drops this trash, and why? I could get mad, but I realized that if he or she didn't litter, accidentally or on purpose, then I wouldn't be able to feel good about picking it up." It's proof, he said, that we are all connected to each other, and dependent on one another, sometimes in the most unlikely of ways."
