OK. Now I think I understand (nobody ever accused me of being smart). Yes, I posted on going from St Paul, MN to Ithaca, NY. I rode most of that route in 2006.
I now understand that you want to go from Ludington, MI to Lockport, NY, where you pick up the (Erie) Canalway Trail: and you want to avoid Canada.
Have you seen the full National Bicycle Network
? It's kinda hidden in the vast ACA web site.
I presume you have looked at the route I took, going north of Lake Erie, and traveling some 300 miles through Ontario.
Note that you can get from Michigan to New York by dropping down to Indiana, Ohio, and Pennsylvania. I presume you have looked at this option, and see that it will still take you through about 30 miles of Canada.
In either event, I understand that you want to avoid exiting and re-entering the US. Sorry, I have no experience in an alternate route.
My recommendation would be to get a passport. Start your paperwork well ahead of time. Or, as Fred suggest, you have one more year to travel without a passport.
I will echo Lite's opinion that you should have a passport. One never knows when an unexpected travel opportunity may present itself.
