I live in St. Anthony. There are a variety of public hunting areas nearby...mud lake, market lake, camas refuge (some areas open to hunting), sand creek wildlife management area, chester wetlands, snake and teton rivers.
I'm new to the area too. I've got a few spots picked out, but I don't make a habit of sharing specifics over the internet (sorry, been burned way too many times
You'll find birds though if you look around a bit. I haven't experienced an opener here, but generally I like to find spots that are isolated and therefore don't get hammered.
