All three of these caves are expected to be linked together, with the two major ones only about 50m apart. Around ninety shorter caves have also been explored and recorded over the twenty year history of expo, and prospecting for new entrances is still an important activity. Very few people, whether undergraduate or old lag, can afford the time to go on expo for the full period.
People come and go, and people pursue their own particular interests within the larger context.
But there has to be some overall strategy and some degree of planning. It is no good putting more resources into rigging than we have manpower to use, nor concentrating on so few goals that the cave is always crowded. So it is important that those doing the organising have a pretty good idea a few weeks before expo of who is going, for how long, and how hard they expect to cave. Nor is it entirely a holiday - once the effort has been put in to rig things, it is important that people get in there and do the work exploring, surveying, photographing and eventually derigging. On expo itself, it is a matter of judging which projects can reasonably be tackled by the number of people present, and suggesting the best lines of attack.
