i think in the matter of safety a half hour before sunrise and a half hour after sunset is reasonable. i talked to a guy who hunted in germany and it seems there hunting education is so tough it allows the person who passes the course the ability to hunt at night. its all about the conditions but i dont think the states will be able to come up with good safe regulations for it. i use to shoot my bow at 3 a.m. at 20 yards in my yard all the time while waiting for my hunting partner to pick me up. for me it was easy to find the front shoulder and adjust for the outline of the deer. i dont think i could shoot game like that though under real conditions. i think part of being ethical is being able to see where the animal goes after being hit. now 10 minutes before legal shooting time during the snow and full moon is a tougher choice. what would you do? in my hunting areas it would be easy for others including rangers and game wardens to figure out who shot what where and at what time so you know what my answer would be. it wouldnt be "but officer my watch said it was legal hunt time" . the challenge and heart break is following the rules too.
