Note on typography: I know this is very common in the US, but I just cannot get used to em-dashes without spaces around them. I tried for ~30secs to figure out what "circling-or" and "cyciling-the" might be, until I realized that those dashes are meant to separate, not join. IMHO "circling - or cycling - the tack" is much easier to read.
