Carp seem to be adaptable fish, unlike many of the so-called "sport fish" we prize. These latter are often one trick ponies. But I think of carp as the "Hogs of the Water."
This is most likely why they are found in so many places, feeding on just about everything, and anything, possible.
At first thought, I wouldn't think they would be readily taken on a fly, but I'm not surprised. And sight fishing is some of the most fun to be had with a rod.
Like deathb4disc suggests, I wouldn't hold out for only that type of fishing. But where it is possible to do it, I wouldn't hold BACK, either!
