We're doing the same thing in a few weeks and our tentative plan is:
Leave TransAm @ Rush Center (actually we stay in LaCrosse, KS overnite) > Great Bend > Lyons > McPherson > Hillsboro > Strong City > Lebo > Garnett > La Cygne > Butler, MO > Clinton, MO
We're moteling it the whole way at a slow pace, I've called ahead to make sure there's lodging in all these towns. My husband will be driving the route in the next few days so I'll post back here if he finds any glitches. We're not getting back on the TA - going south on the Mississippi River Trail in St. Louis, heading to South Carolina.
Maybe we'll see ya out there - we're leaving Pueblo Sept 2.
