Something does indeed always crop up!
There is a lot of out of the way stuff left in SC, which does not get visitors that often - its just tricky or needs more than the usual equip to get to.
And then there is also a lot of interesting rises left that need investigating, they need scaffold poles and lots of bolting - a group effort may be needed to do some of those, then also be prepared for it not going anywhere - many a time spent doing something that took ages, and then nothing, still fun though - because you did it.
