Advisory: we ran alt 49 out of park into Lineville. It had recently been tar and graveled; yuck. The rest if the road was great.
We did this road on 2 Harleys in 09, had a good time, really enjoyed the roads, much better than in Florida! Sweeping curves and fairly good surface, some stunning views.
Really good combination of great, scenery, wide well paved road and nice corners, well worth a look
