Not that ridiculous if you think about it from the viewpoint of what the law is trying to do. This type of law is designed to try and keep an unscrupulous hunter from killing a deer out of season, or after filling his buck tag, then lopping off the head and saying "I found it dead by the side of the road". It isn't perfect, but the thought is that it should help cut down on this type of unethical behavior while still allowing an honest person the chance to make use of a roadkill. If you think about what the law is [b]trying[/] to do, it isn't ridiculous. Check your local laws about this, in some places there is some version of the rule mentioned in this thread, in others it is illegal to take any part of a roadkilled animal and in some a road kill is fair game for any and all comers.
