First off, I really like this blog. Really well written and entertaining. He has good advice to boot. While I live within 10 miles of my workplace, there's no way I could bike it (a 25 minute ride all in parks). Reason being, I live in Arizona and it's about 105 at 9-10am in the summer. There's no way I'm going to peddle my way to work in that heat let alone ride home in it. I'm sure many people who live in cold climates (no idea what that's like) would object too.
