<p>My daughter has done the Elon shuttle when the times worked out, and once she shared a cab with 2 friends. </p>
<p>Her sorority has a private FB group and often the girls will post when they are going to/from the airport to coordinate car-pools or share cabs.</p>
<p>This year she has a car, and one weekend she drove a friend to the airport - the girl paid her $40, which covered her gas and gave her a payment for her time (2 hours round-trip to/from RDU) but was about half the cost of a cab. They both won.</p>
