Well this is totally wrong.
Like I said I carry my gear everywhere. Wading, floating, everywhere. It does take a commitment to use it though. It takes time to pull it out of a waterproof bag/case and take a picture. It's not quick and easy like a point and shoot, but you can get some amazing pictures from a DSLR that you just won't get from a point and shoot. If you are just looking for snapshots then a p&s is perfect and the best option. If you want to make art then you need a DSLR. Al makes some amazing art on canvas, I like to try to make it with a camera. Last float I had the body, 3 lenses, external flash, wireless remotes and a tripod. It's something I love to do.
