The left knee was smarting a bit, causing me to ponder the idea of pushing 10 miles on my runs. We'll see.
I read an article on biking vs. cars that JT referenced, and the more I think about it, the more awful it becomes. Whether something benefits "society" is not an effective way of judging any issue, and it certainly leaves one wondering why we ever developed cars, let alone aircraft. That one's on the backlog for later.
