Ewest, I'll defer to your expertise on this one, I've never heard of any planted crop being considered baiting though. In fact it is most often what's suggested.
Ewest is dead on about the Federal Migratory bird laws! I was 24 and using a Friends shotgun while dove hunting and never thought to check the magazine for a plug. I chambered a round when the Game warden popped the 5th shell into the magazine.....no plug! I was legal in all other requirements.
Charged in federal court....$10 fine 6 months SUPERVISED probation!!! The PO was at my work 3 times per week for all 6 months....those boys get serious!
