I know we are already carrying too much electronics. But if it is necessary to carry a laptop or anything else that must stay dry this new piece of gear from Pelican Case could be just the thing: http://www.canoerootsmag.com/blogs/gear/1968-check-this-out-a-waterproof-pelican-case-built-into-a-backpack.html

Why would anyone carry a laptop? I have to carry one every time I get a chance to do a WaterTribe event. If there is some technical glitch during the event, all I have to do is paddle to the nearest cell phone zone and fix it. Or maybe you're making a documentary and want to edit some clips every night. Or maybe you just need to carry it around a campus. Who knows?
