I take 99% of my pics in the water. Almost never keep a trout. My wife doesn't like the taste of rainbows and I don't like keeping the big browns. You can keep whatever you want. If you are "PUT AND TAKE" with stockers go for it. If you are killing 30" brown trout I have a problem with that. We fly fish mostly and mortality is minimal. I have a lot people that bait fish on my boat ramp. I go down there and see trout floating belly up all the time. Years ago I didnt care I ate everything I caught. There are so many fishermen now its a burden on the fishery. I have a place on the river and fish a lot so preserving what I can for another day is paramount. We do keep striper, white bass and walleye however. Just not the trout. You paid for a license to catch trout use it how you see fit. I think also that if I was going somewhere once or twice a year or maybe even more I probably wouldn't be as attached to fishery as I am. You're right its not any of my business what fish you keep.
