Hey, it could be worse. I've attended a match or two in the Peoples Republic of New York over the years and they've had this law on the books forever.
Applicable NYS Law - NY Penal Code 265.20(13) which states:
"Possession of pistols and revolvers by a person who is a nonresident of this state [is permitted] while attending or traveling to or from, an organized competitive pistol match or league competition under auspices of, or approved by, the National Rifle Association and in which he is a competitor, within forty-eight hours of such event or by a person who is a non-resident of the state while attending or traveling to or from an organized match sanctioned by the International Handgun Metallic Silhouette Association and in which he is a competitor, within forty-eight hours of such event, provided that he has not been previously convicted of a felony or a crime which, if committed in New York, would constitute a felony, and further provided that the pistols or revolvers are transported unloaded in a locked opaque container together with a copy of the match program, match schedule or match registration card. Such documentation shall constitute prima facie evidence of exemption, providing that such person also has in his possession a pistol license or firearms registration card issued in accordance with the laws of his place of residence."
Luckily my CCW is good in all 50 states
