Despite the general discomfort, wind noise, and terrible gas mileage, I always miss having my Jeep.

This is a very mild example; the Daniel Boone National Forest is overrun with interesting roads, including the Daniel Boone Backcountry Byway.

Alas, my rental Kia Forte is no vehicle in which to go deep woods exploring.
