Supramax - yeah, i've heard the saying. But what i said in my post is that my commute is conducive to not needing to carry it, so i don't. So for you to understand it: "it's okay if you need it and don't have it, because there's a bike shop/gas station/etc. a couple blocks away."
Perhaps I'm missing something, but I fail to see the point in packing all that junk when I'm riding a few miles through the city, while passing a couple of bike stores, to a place where i can store supplies, all the while having the last ditch option of just hopping on the bus that shadows my route. But hey, to each his own, right?
OP, i'm glad you have it figured out. Enjoy the ride.
