Chain pickerel in the first pic -- very sure of it (member of the Pike family). Sauger for sure in the second.
Somebody is fishing further east by the looks of it.
Live bait rigs are $$$ and a hassel, but if you're making the trip out of town, why not. On a good day, the right lure for the conditions will work just as good, but if anybody is willing to put up with the hassel of minnow buckets, airation, pickup up the bait, disposing of the bait, they are almost guarenteed fish in shitty conditions.
Scond pick is just braided line and what looks like a pretty standard tandem/pickeral rig.
Congratulations to your friend. That is a dandy of chain pickeral.
