From Phil Runkel on 25 October 97.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Bruce Gregory on 24 Oct tells Rick Marken that his post of 24 Oct  
on "PCT and the art of motorcycle maintenance" (actually on types of  
control in the hierarchy and consciousness) was very nice, I thought so  
too.
