Interesting. Do other people pack clothes the night before? Seems like they'd be wrinkled, in my flying experience--but I've never tried it biking.
My commute's short, but hilly so I don't wear street clothes and definitely need a shower afterward. Unfortunately, if I shaved the night before I'd be pretty stubbly by the day's end.
I do seem to spend lots of time with little items such as cell phone, wallet, badge, keys (gotta lock up the bike), etc. I've been thinking about a little bag to consolidate these but it seems the most time is spent getting these into the pockets. Keep 'em coming!
