Nebraska really is a fun trip for us. There's lots of deer, the landowners and very welcoming and supportive of getting the kids out hunting. We usually have permission to hunt several thousand acres of agricultural fields and rolling hills without any trespass fees. Last year, after giving us permission to hunt his property one rancher even spent a couple of hours driving us around in his truck showing us places to hunt (tree stands, ground blinds, etc.) and suggesting tactics to get the boys (and the dads, of course) into deer. I consider these folks friends--they're on the Christmas card list. The hospitality is fantastic!
If you can swing the trip you should give it a go. And when your kids are old enough it's a must do annual trip. Oh, and to sweeten the youth hunting pot, the youth tags for non-residents are only $6. Ya...$6 for a tag to shoot 2 deer. I wish more states provided low cost tags for kids!
