Was a historic event!!! There was an orange flare go off at approximately 10am, but on the radio they were still talking about delaying for 1 hour. #??? The Water Police were kept very busy hearding people out of the exclusion zone. It did go down at approximately 10.10am- without the second flare, but if you were listening to channel 66, there was plenty of info,a running commentary on the whales, and a countdown. It was nearly delayed an hour by the fools inside the exclusion zone and the pod of whales, which were headed directly for the site. Fortunately, the charges were set off before the whales arrived! It sat on the surface for just over 1 minute before it started to sink, bow first. Once it started to go down, the whole event was over rather quickly, then the race for the boat ramp was on!!! That was a pretty scary experience! We only sat for approx 30 mins in the line at the boat ramp, not bad considering the number of traliers parked around there. A once in a lifetime experience, well worth the effort!! You shuda been there Dug!!!
