Charley, LVCamaro and all,
I spoke with Helen today, I understand the tour is coming up Hwy 67 out of St. Louis, to Davenport. That is the route I always take to and from to LaHarpe from St. Louis. You will be just 12 miles or so from LaHarpe. The good new is Helen and Nancy will be joining the tour just north of Macomb, at the junction of Hwy 67 and Hwy 9. She will be in her '02 ZL1.
I am planning on coming from the North, and will hopefully avoid some of the traffic if I'm early enough. Is Matt Murphy on the tour?
ps. when you come through Beardstown, the old track is just south of town, about a mile east. Any old timer in town will know exactly. This pic is from Beardstown, 8/10/67.
