I am a professional photographer and shoot Canon SLR's. I think both Canon and Nikon make fantastic SLR cameras, but I rarely bring my expensive SLR with me hunting or fishing. To do so means I have to lug a waterproof pelican case along, plus the cameras are big and bulky.
Instead, I have been using a "hybrid" camera which combines the best features of an SLR and a point & shoot. My camera is the Canon SX20IS, which is no longer made... but they have the SX30IS now which has even more zoom. These cameras are smaller than an SLR, have more zoom than a SLR 300mm lens and all the features of an SLR body, plus they cost a lot less!
I love my SLR, but when I am out in the marsh my SX20IS is smaller, less expensive and still takes fantastic photos. The SX30IS has a 30x optical zoom and does video as well, all for less than $500. Just another option to keep in mind....
