OK Fulk, I'll come clean - the "circumstances" involved a lass I'd taken a shine to, so I was quite motivated to keep the dastardly secret . . . . :halo:
What got me rumbled in the end was a genuine logged "novice dive" to -85 m in a big Italian spring. (The CDG member I was cave diving with that day happened to be a BSAC instructor, so he mischievously suggested it could count towards my novice qualification and was legitimately able to sign off the dive in my BSAC logbook.) Our Diving Officer later gave me a right telling off for missing out a decimal point and I just couldn't keep my face straight. He was a grand bloke and saw the amusing side of it immediately.
Seriously though, that BSAC branch was a great bunch of folk and I thoroughly enjoyed being a member for a year or two.
Ewan, the only reason I've (so far) not suggested you might like to join us when our group is on a diving project is because most of the time I operate in the Dales (a fair journey for you) and we tend to decide where we're going at the very last minute (in order to choose the optimum site for the conditions on any day). Also, a lot of the time we just carry our own stuff. However I've not forgotten your offer and (when things work out) I'll try and get in touch with enough notice for you to come along. In the meantime, keep on diving. It really is hours in the water that counts.
