It is really that nice on BART that you'd look at someone stinky in cycling clothes as a pain?

Over here (and throughout Europe) I find that everyone stinks on the subway, especially during the summers.

Are you sure this isn't only in your head?

I tend to commute every day and shower only on the days that I teach (or have an important meeting). Most others, I just stay in cycling clothes most of the day. My other colleagues are the same.
