Summer and fall offer excellent driving conditions, though fall foliage season brings heavier traffic on scenic routes. Spring can bring unpredictable rain and residual freeze-thaw damage to road surfaces.

Starting early in the morning typically avoids afternoon storm development and rush-hour congestion near urban areas.
