I carry everywhere including NY.
We carry guns because there is a chance that we may be harmed or killed. That's why we choose to carry a self defense side arm. So you have to decide what concerns you more; the chance that you may suffer harm if you can't defend yourself with a gun, versus the chance that you may suffer legal troubles if you do carry a gun.
Not merely legal troubles, but getting nasty infectious diseases and foodborne illness during your stay at Riker's. No thanks!
