You guy's have to bring it to extremes don't ya.
Did anyone come knock on your door? Did you turn in someone you saw at the range using one?
If you find a feather use it. Just tell the SWAT Team at your door the truth, You found it. The Judge will probably toss out the charge and you'll only be responsible for court fees and towing.(+ the weekend in jail will help sober you up)
If you have 100 feathers and sell them on Ebay, that's a different issue,, or does somehow the collective here not understand that?
How has this been lost?
