Well, to answer one question, my Nikon D80 does not have video capabilities, but the D90 does... so I would bring a Canon HD30 which is not too heavy, but a bit bulky. It shoots digital tapes, not the newer flash storage ones.  It would be worth bringing a digital video camera because the videos of trip would be great to see afterwords.  My binocs are Canon 10x30 power with Image Stabilization (IS).  For those who use IS, it is a great treat to view images without the shake and would be an advantage for spotting portages from a canoe, but they are not that high powered IMO.

I just weighed everything together, together they are like approximately 6.5 lbs.   I would hate to go on a hike and just carry these.. just much weight.  

On the other hand, the images from the Nikon (18-200mm zoom) are really great.  The zoom is really useful and would be great if spotting an eagle or moose not to mention all the other great things about the camera.
