I am starting my first food plot this year and I'll be planting this to start...

I don't know what the laws in LA are regarding corn/supplemental feeding, but here in Indiana it is legal to dump out corn/minerals during the off season. It has to be removed during the hunting season, but it is a good way to keep the deer hanging around during the summer. One thing that the deer really seem to like is Record Rack Golden Deer Nuggets from Sportsman's Choice.

I have also heard good things about Deer Chow from Purina.
