What kind of drive is this?

Expect a turn-heavy local drive that demands your full attention as you transition between larger interstates and smaller corridors. Unlike a monotonous highway cruise, this route shifts gears frequently, requiring you to navigate various turns as you move through different segments of the state.

You will find that the rhythm of the drive changes as you leave the start point and navigate toward the destination. Staying alert at the wheel is key, as the local road sections offer a much different experience than the standard interstate flow.
