From Guns.com:

That might sound odd, but it actually makes quite a bit of sense. Utah concealed carry permits are recognized in 31 states, so a permit carrier can cross most state lines without too much concern for variable state gun laws. It’s a bit ironic considering that Illinois is the only state that doesn’t permit concealed carry, but where there’s a will there’s a way. Illinois citizens can still prepare for trips abroad into concealed carry-friendly states.
