So final numbers, 615 on the larger Aegis CG, plus presumably at least a few people who only did the Azimuth one ... somewhat up on the previous sampling CG despite the general decline in CG participation since then.The Colonia sampling CG (the most recent one before this, almost 2.5 years ago) had 539 participants - less cost in terms of start-up equipment, and the NSP life being sampled didn't seem to object, but equally the size of the trip needed means that you couldn't meaningfully spend much under 8 hours on it if you wanted to participate at all, unless you were able to find a carrier to get a lift with.
For a CG that's not just "haul this" or "shoot that", that's pretty good going!
