RAGBRAI to Mark (Brattleburough)

This is an idea I have for Steven's Point, Wisc to Brattleborough, VT. It uses the Adventure Cycling Northern Tier Section 10 and Lake Erie Connector maps, and then follows NY Bike Route #5 (Erie Canal mostly). I need Iris to find me her Adventure Cycling Michigan maps. Any of you tour in this area and have advice for the route? I'll have about 25ish days and this is only 1,200 mile of mostly flat, so I could scenic it up a bit.

This will be considerably more laid back then the first half of the ride I think.  I plan to get to Steven's Point by taking the Team RoadShow bus up after RAGBRAI.
