When we vacationed last July with Cindy and Ray, Cindy had just bought a mobile GPS to help her navigate our Sacramento>Carmel>Yosemite>Folsom road trip in case our cars became separated. As I recall, she had some problems with it… beginning with getting it to stick to her windshield and later with its disagreeing with the fancy schmancy GPS in our car. So when I saw this Randall Munroe ‘toon, I immediately thought of them… and the wonderful memories came rushing back.
