PA, for one, and in fact it is legal to drink while carrying. Oddly, we have no more blood in the streets, nor in our bars, than any other state...and a lot less than some.
We have this debate every few months. It is a worry that bothers a lot of people way out of proportion to how things actually ARE.
So, if I'm going to visit a place would I rather be armed, in case I'm attacked, or unarmed, in case I'm attacked? Question really seems quite simple to me.
I'm not a fighter, not a brawler or trouble-maker. If someone attacks me, I do reserve the right to defend myself in any place that might happen, with the most effective tool I have.
It is a logical disconnect to say, "wow, I'm likely to be attacked here! Sure am glad I don't have a weapon on me!" What, are we buying into the myth that it's ok to be in bar fights because they'll probably just beat you up "a little" and you wouldn't want to introduce a gun into a little gentlemanly arse-whoopin'?
If you think you're likely to be attacked DON'T GO THERE.
If you are willing to go to a place, go armed.
