RE: break the law
I probably would not knowingly violate the laws on legal shooting hours, but I wouldn't look down on or turn in someone who shot a little before or a little after legal shooting hours. My opinion is I have too much to lose by breaking such laws, even if I don't think it is a big deal and a poor law. I wouldn't want them, for example, to confiscate the rifle that my father built because I used it in a hunting game violation.
Where I hunt deer, Oklahoma, shooting hours extend from 30 minutes before sunrise to 30 minutes after sundown. This seems a very good standard. I find at 30 minutes after sundown I really can't see well enough any more (I can see well enough through my scope but not with my unaided eye), which is when I quit hunting. I took a doe this year at 20 minutes after sundown and my first deer three years ago was taken at 15 minutes after sundown -- legal, as I said above, in my hunting area in Oklahoma but is sounds like it would be illegal in some of your hunting areas.
