 <dd>Once the cave starts to get significant (ie. anything which requires getting changed or rigging), it needs good documentation. This is mostly a matter of doing a cave survey, a guidebook description and usually a surface survey. The first time you go to explore a poorly documented question mark, you 	will realise how important this is, and it also makes for having a pretty survey on your wall to support your bullshit. For 1998, the surveying guide has been split into easily digestible chunks, including pages specifically intended for people who <a href="survey/what.htm">haven't surveyed before</a>.</dd>

 <dd>You fall and break your leg &ndash; probably need a little help to get out of the 	cave ? How would you feel if everyone at this stage took the rescue guide into 	Hilde's bar and started reading about what to do ? Not a happy prospect, is it 	&ndash; so in the hope that it is <strong>not</strong> you who gets hurt, we suggest you read 	  this <strong>now</strong> so you know what to do. It may well help you if it <strong>is</strong> you who gets injured, and may even help prevent that from happening. So don't 	skip it !</dd>
