OWL stands for "on site weather logger." My understanding is that these are weather monitoring stations centered around an M100.
For years they would dial into the Club100 BBS to upload their data. I think Rick took the BBS down as the OWLs eventually all went offline. There might be more information in the email archives, maybe check GMANE. I used Google site search to find one mention at club100 http://www.club100.org/stories/01/feature.html -- John. > >
