My sarcasm is primarily because I want to catch fish in their native habitat. If it's not native, it's feral. I enjoy trout fishing here in Missouri, but they're not native and I so don't hold my interest as much as catching what was here when before the white man arrived. When I go to the Rockies, I want to catch cutthroat. When I go to Appalachia, I want to catch Brookies. Northern Pike in Canada, etc.
That said, I have no fire in my belly to travel to Asia to catch carp. But they are on my bucket list to catch on the fly locally this year. Just for the ugly fun of it.
