As some one who has scrimped and saved for every little piddling upgrade I've made, it makes me pretty angry when I see bikes that have just been chained and forgotten. Up here on the Duke campus, of which I am not an attendee but pass through regularly, it is common to find poor, decrepit, machines just left to rust. I totally agree that people have rights to their own property and if they wish to leave their bikes out in the weather, it is little more than a minor nuisance and of no consequence to me. I am jealous, however, that their financial situation allows them to abandon bikes that I would cherish in part or whole. Ah well, the "have"s and the "have nots" are always at odds. I'm sure I waste plenty without even giving a second thought, but my bike is important to me so that, in part, explains my heightened awareness of this kind of waste.
