I sighed. I’d been to six different Rent-A-Runabout agencies already that day, and was getting more than a little bit frustrated. I’d started with those closest to home and worked outward in a spiral from there, without any success. Now that I was here, I didn’t want to fight the airport traffic and pay SeaTac’s exorbitant parking fees twice. Besides, I had a strong hunch about this one. This time, I was going to listen to my instincts.
