Going to pick up car at end of month and would like to not take freeway home. Myrtle Beach SC to Boise ID. I have never been east of Tennessee and really not explored any roads twisty from Colorado east. A cross country drive, 2300 to 3000 miles in under 5 days in a new GT500 CFTP and no freeway. What roads back east are fun, fast, and curvy?
