Saturday evening as the storm was subsiding, the communication lines went dead out here at Race Rocks. After trying all the normal fixes on my side, I was informed via cellphone that the problem lay at Pearson College. The College had lost power from some internal breakdown, and so no internet or phone line was being sent my way over the air. Once things were up and running again this morning, I was able to reestablish connection to the internet and phone lines.

Rather than submitting a log entry for each missed day, I will simply provide a summary of each day’s main events. And pictures as always!

  • It was neat to watch more than fifteen fishing boats head through Race Passage at 7:15 in the partial darkness of sunrise.
  • Two boats were fishing in the Rockfish Conservation Area, mostly between the Rosedale Rock and the South Islands for several hours today.
  • I identified them as best I could, and reported them to the DFO.

  • The two offending boats made no such effort, drifting about all over the southern part of the reserve.
  • Several ecotours came by today.
  • In the evening one small aluminium boat ripped through the reserve well above the speed limit. Presumably he was late for supper?
