What kind of drive is this?
Expect a turn-heavy local drive rather than a high-speed interstate cruise.

Instead, the personality of this drive is defined by frequent turns and changing traffic patterns as you transition out of Philadelphia. Staying alert is essential, as the constant shifting between local roads requires your full attention throughout the 28-minute duration.
90% highway — fuel and pacing are the main things to plan.
