Hmmm... ! Something that I've heard a lot about and not really dived would be the north American cool-temperate areas. Great Lakes and St Lawrence (wooferbitch territory) ? Pacific Northwest (LCF's area) ? Nova Scotia (not sure who's there) ? I don't know what dive infrastructure there is around Nova Scotia but the nitrox-depth wrecks and like big marine life looked great if a talk at a recent dive show was to be believed.

Now you've got me thinking :-)

By the way, do you have a news mailing list on your site? I couldn't see one but might have just missed it.
