Three years ago, I could of gave you a list of 40 farmers that would of let you hunt with out a problem, Today I can only give you an outfitter and some public land suggestions.

They are pretty good bunch with some exceptional hunting.

Your son can hunt in the youth only season as well in MO. The public land isn't really that busy from what I've seen, and for $17 (any sex tag)you cant go wrong (that is non-resident as well). This year I believe you may also purchase a bonus doe tag for youth season $7. You also get a trukey tag with the first deer tag purchase.

If you need more details or suggestions for public land in northern Mo, send me a pm, as I tend to lose threads that I reply too.
