Thank you. I will let this be a lesson to me. Don't be surprised if I turn up at your place of business one of these lunch breaks, having finally found you by systematically casing each and every nearby bank. I will tell you that your understanding of the ride difference was correct and that I was mistaken. I may or may not say that I will continue efforts to give a shit about cycling related issues which may be of no personal import but matter to others, and to refer questions to more interested and/or knowledgeable co workers where appropriate; at least, no more guessing.
You should get a cross bike.
