It has the info and it looks good for bringing it back
I just went through customs at 1000 Islands in NY (I-81) on Sept 11. When you get to the booth, tell the person that you were hunting moose. The American customs people were great and friendly (unlike going into Canada). He sent us to park, we went inside, they had the USFWS form half filled out, we filled out the rest and were on our way. They never even looked at our meat, racks, guns, etc. Short, sweet, to the point. Good luck on your hunt. Just a note of caution, don't know where you are in NY but all the guys that crossed due south of Montreal waited like 1.5 plus hours each way. We were 20 min into Canada and 30 out including waiting in line to get to the initial screener and then into the buildings at the I-81 crossing.
