Mmmmm In 'N Out Burger You can walk the whole way from T6/7/8 to In 'N Out and back. Remember the saying "Should we walk, or do we have time to take the bus?"

It takes around 20 minutes to walk there if you're fast and 30 minutes at a normal pace. For additional exercise, don't cut across the parking garage and take the long way -- T6, T5, T4, TBIT, T3, T2, T1.
