Actually ... yes. Well ... I had a handlebar bag too. I created that list when I got back from Australia last year ... based on what I took with me to Australia. I think I've added one or two things to the list since that trip, but not much.

A lot of that stuff is really quite small. I buy the trial-sized versions of stuff from pharmacies etc. ... and try to get the smallest version of everything I can find. For example, the sewing kit I mention there is a tiny little plastic "envelope" about 2"x2" and virtually flat which contains a card with thread wrapped around it, a couple of needles, and maybe one or two other things. Because it is so flat and compact, it takes up next to no room at all. A lot of my stuff is like that.
