Alot we do is under the cover of darkness. Permits etc? Fish and game cannot always come to our aid.
If you are not going to terminate this possum, find a good place and release it....period! Do not have to say anything to anybody!
What YOU do "under the cover of darkness", is break the law, and possibly set up a great way to spread disease and a lot if problems.
Maybe it's time to add a little thread and educate a little.

Please don't encourage others to break the law. They are there to protect us AND our livestock.
