Woohoo Dianyla - but of Course you can take responsibility for it! Good on you!!....and gee isn't That a shame that your office needs to get another bike lock??!
and Trek I Love the poster idea!!
and Waverly: you might try riding it on a quiet day say like early on a Sat or Sun morning and see how comfortable you are with the route. My first response to your question was Absolutely I'd ride it - but I ride busy streets every day so I don't think about it. I do - however - make myself visible by wearing bright colours, sitting up at any questionable intersetions, and living in a basically bike friendly community!
Life should NOT be a journey to the grave with the intention of arriving safely in an attractive and well preserved body, but rather to skid in sideways, champagne in one hand, strawberries in the other, body thoroughly used up, totally worn out and screaming: "Yeah Baby! What a Ride!"
