You can find local fly fishing that's not too much of a drive and won't be shoulder to shoulder either, just need a good friend to be your local guide until you get your feet wet, so to speak.
Same for bowhunting, there's a couple spots that aren't THAT bad, and are OTC, within decent proximity, and if you don't like those there's plenty of spots you can find that aren't overcrowded within 2-3 hours drive, just may have to hike a bit after you get to the trailhead.
I-70 ski traffic and summer traffic can be horrid but you'll learn how to time it to make it less so.
Traffic sucks, drivers are rude, just like every major metro area in the world, but probably nowhere NEAR DC driving, it's probably actually pretty tame compared to what you had there.
There's also some smaller mountain communities that would put you in between Broomfield and everything you like to do without a terrible commute, would be worth looking at.
It'll check off a lot of your boxes and the local politics could use you
Hell, I'm moving out of state soon anyway, if you hit me up I'll give you some fun little local places to fish to get you started.
Bowhunting you're on your own because I'll be back to my old haunts for that

but there's elk all over the place, just have to learn how to play them, which has been fun for me the last 9 years here.
