As I write this, I’m in the air between San Diego and Atlanta on my way home to Mobile after presenting at a conference. The fact that I’m traveling today has a lot to do with my grandmother. She gave me wanderlust at a young age when she took me to Cozumel, Mexico and one day we flew in a rickety old plane into the Yucatan and landed on a grass runway to see the ruins of Chichen Itza.
