Great suggestions folks! I will definitely start retrofitting my bike now that the weather is warmer and commuting is so much easier without all the winter gear.

Alfster-I love the idea of having a trailer. Should have thought of that! How heavy is it and easy to maneuver around stairs? (I live in an walkup apartment.)

badmother- That's a terrific bike! Did you retro fit it yourself? And your dog is adorable!

PomPilot- I've seen these for babies, but never dogs. Just might consider getting one, but not sure if the doggie is going to grow any bigger. That could be a funny sight though carrying a 25+ lbs dog strapped to my tummy.
