I brought a semi dry 7mm wetsuit, a full hood, and as a backup a 2nd shortie with hood that was 5.5mm (or a total of 12.5mm of neoprene). That was a wise decision, the semi-dry 7mm wasn't much warmer than a 7mm, and after my first dive, I was very cold, so I put the 2nd wetsuit on top.
This turned out to be barely enough, and I was still cold on most of the dives, but it turns out the temperature got as low as 13C (55F). It was sad when I saw my computer say 16C (60F) and that felt warm, but the 2 wet suits, tight hood, and 28lbs of lead just weren't comfortable or fun.

All that said, we had above average vis (which means somewhat poor instead of very poor ;) ), and no current, so we got lucky with the conditions actually being as good as they could have been for there (except the temps).

On the first day, we did a couple of kelp dives first, and the Yukon and Ruby in the afternoon. On the second morning, double dive of the Yukon on nitrox, and finished up with the Ruby again, where I took a crap on the toilet :)

Unfortunately most of my pictures are crap because my real camera lens kept fogging up. I used my gopro as a backup, and the nicer pictures are from Arturo.

there we so many lobsters, it wasn't even funny:
