As someone who shoots video for a living and has done so for nearly 20 years...let me say this: I love good still images. I use them often in my video even when I have the same shots on video. Like troutbert said, its an impact thing. But there are times, and I think most of them, when you just can't do justice to an event with a still image. Thats why even when I edit stills I have to add audio. Nothing worse than watching uncle Charlie's slide shows.
On my last trip to Idaho all I took along was a still. I was more then pleased with what I brought home. I wouldn't have done it any other way, either because like someone else said, I just don't like to bother. When you shoot video for a living its not always something you want to do in your free time.
It sounds like curtrein would like to go above and beyond the call with this which is why he mentioned wanting to edit. My guess is that curtrein already has a still camera. I'd be very interested to see how his videos turn out. He can correct me if i'm wrong but i'm guessing he is a younger guy and like many these days, very capable of putting something far more interesting then just video of him and his buddies fishing. I've seen some amazingly good videos done recently by "kids" and the things they like to do. I would not discourage this.
As for the suggestion of the camcorders with the internal drive...not yet and definitely not in a situation where you could drop it on the ground or in the water. I mean heck, if I'm going to drop a camera and break it or ruin it, I'd at least like to be able to get the video that I went thru so much trouble to get. mini DV will give you a very good quality image and less headaches in the computer. Plus, if you are out for a couple days in a row, you don't have to worry about not being able to shoot any more once your camera is full. Buy your camera from Tigerdirect.com, your tapes on ebay..and an extra battery or 2 on ebay will set you back less than 10 bucks. You will want a polarizing filter for your camera though if you will be shooting fishing. Ebay, as well.
