Just spent a bit of time with Mr Brock.
I'm not going to do an in-depth write up a la WWD, suffice to say they were some of the most useful and best value three days I've ever spent.
Thanks to the various YDers that popped by or contacted me, especially to Gman whose invitation to beers with his dive club was welcome but not taken up in the end.
Mention also to some bloke called Jones, who came in and scoffed the biscuits I'd brought...
Many, many thanks to Neil (and Maggie), who seem to have far more patience with the likes of me than I have. Top team, super-helpful, great set up.
As in WWD's post:
