RE: which crop during the fall will draw the most deer???
I think its tough to beat apples - especially an old orchard setting.
Regardless of what else the deer are eating - they so often seem to stage in the overgrown apple orchards before dark - and before bedding down in the morning. Apples are ALWAYS a good snack, and the deer are comfortable in the cover they provide.
I like Rye for a fall plot - but usually hunt the apple areas 1st.
