Here's one for you, overanout! 

Done by Fiona 6 & Lewis 3 in April 2007

We had read that conditions down the hole were a bit cramped so it made sense to send the smallest stonefielder (aged 3) down! This caused more than a little sibbling rivalry so his 6 year old sister also joined him in the whale. 66 has been claimed as the age of the oldest finder I assume 3 is the youngest?
This was superb fun, I'm afraid they were rather excited on reaching the treasure to be discrete thankfully there was no one else around.
For anyone thinking of calling social services we have done a lot of climbing and both kids were belayed with chest harnesses - I wouldn't recommend taking small kids to this one otherwise.
Took TB left swops
Excellent fun- Many thanks
