i went diving today, with a good size group of people (i think 9 of us in total). all of us were at a different experience level (brand new diver to assistant instructor, single tank to twinset to rebreather) from a variety of different agencies (gue, padi, bsac, saa). thing is, it didn't matter our level of experience or what agency we trained or didn't train with. what mattered was we were all psychotic enough to go to wraysbury and freeze our asses off in 4*c water. and i think we all had a fairly decent day, despite suit and glove leaks. some skills practice may have been cocked up, hands may have lost feeling, but it was fun. and we all enjoyed a couple of pints after in the pub. stories and experiences were shared, and many laughs were had. It didn't matter that there were 30+ years age difference between the youngest and oldest divers in the group, some people knew each other, others didn't. it was the camaraderie that was there. New friendships and buddy pairs/groups were forged. This is what a day of diving should be like.
