lol BC, you hunt a whole different kinda varmint than most, bro...you need that silencer. Nutria don't shoot back. Check out Canadian Tactical, I've heard you guys might have been putting them to use.
Around here at least, the crackle of a 22 has never hurt any of my hunting, its taken a lot of birds and Nutria-like animals for me. There are a couple peskier varmints around here (4 legged) that could stand to be removed but I would want the silencer on something with a little more punch than 22 lr...Might as well. Not having a silencer never hurt anyway.
Oh yeah, while we're onto illegal topics, how can I convert my SKS to...Kidding, kidding! That one pops up on lots of forums too...
