hey MM and Veronica...you both have very different commutes, but I think that the planning and intent are similar.
Just prep for it and I think that you'll find it's almost addictive! I know that when I bike commute, I have to drop off laptop computer and work clothes in locker ahead of time, and it makes for an earlier wake up alarm, but it's SO worth it! I start the day with an amazing amount of energy (co-workers groan at my energetic and cheery greetings, responding with, "you rode in on your bike today, didn't you?") and I find that, from the early afternoon on, I'm thinking of and yearning to get back on my bike for the return trip - it's an elixir!
You go, girls!
