Recall at the 50th Anniversary event in Millau, S. France, the Speleo Secours Francais laid on a "reverse rescue" wherein 3 (IIRC) disabled people who had willingly entered a raffle to win one of 3 places on a trip deep into a cave on rope were all escorted by a large rescue team, with in-cave restroom breaks in ad hoc hospitality tents, down to an impressive gallery/chamber, before being escorted back out again. Cave rescue hosted the event as a useful training exercise while making 3 disabled people's dreams of venturing into a cave become real. Well done to all involved, was our opinion on seeing the whole shebang. Very impressive.
