The New and Improved Cornelius-Schefflin road is indeed a wonder. One can now go from Roy Rd to the now-protected left turn onto Wren Rd - a very pretty stretch in every season. The red clover fields in late spring are particularly breathtaking.
I had heard (do not quote me on this) that whenever a county road out there is up for repavement, it will also get proper shoulders. As most of them have no shoulders, this is great!
Butner. Ah, how special. Parts of Walker Rd, as well. I only ride on Butner from the SW Downing intersection to SW Huntington; then I drop down to Park Way - gets me to the same place, and is wider and has slower traffic.
