New Hampshire Public radio has a lot of local news and features too, which I can't hear anywhere else. I'm sure other markets are the same.
You can get it on Alexa too because most of the shows are also podcasts which is also great.
I've also heard a lot from my conservative friends that NPR is too liberal but to be honest, I haven't seen that at all. The more entertainment like programs like "Wait Wait" do sometimes have liberal jokes but I think anyone who can take a joke would laugh at them even if they are conservative.[1]
[1] I'm a Libertarian and thus social liberal and economically conservative which puts me in the great position of being able to laugh at jokes at the expense of either of the two major parties.
