For the benefit of the all forum, what are you talking about? What Caving Club are we talking about here? I can't follow you
To be honest, I don't think detail is going to benefit anyone ...
I suspect that mattc was talking about a particular rider with a twin reputation for being, um, careful, and a robust caver. I assume that said rider has previously booked accommodation in caving club huts near to whatever event he plans to ride, paying whatever modest sum he is charged as a guest with reciprocal rights as a member of his own local club.
I've wondered about doing something similar using mountaineering club huts, but have never quite got round to it.
