My pet theory lately is that slack here in Enterprise Channel is about 2 hours after the published Race Passage slack. Slack at Race Passage today (Oct. 1, 2010) was at noon so I came for a dive at Enterprise Channel at 2:00 pm. The current was almost non-existent. Visibility was 20-30 feet, which is as good as it gets here. This place looked even more colourful and full of fish than usual. I saw a small octopus out in the open. I didn't notice it until it squirted a cloud of ink right in front of my face.
