Usually I bike w/ 6 yr old to his school in minimal clothing and add more as I think I need when it's time to leave there. Today when it was time to leave there it was clear that it was time to fix my rear inner tube, so I went home, did that, decided to continue to skip jacket/tights. No real big deal at ride in time but it was in the 30s apparently which explains why it felt brisker than usual. But it was sunny baby! Or, at least bright reflecting off the cloudcover.
