I smiled and laughed during my sister's recent interview on the NPR radio show "On Point." She talked with the host about her new book, "Are We There Yet?"

It was fun to hear people's memories of their car travel trips.

If you have a hard time hearing it with their Real Audio or Windows Media, click on their podcast menu, and listen to the interview through iTunes.

Her book was just published by the University Press of Kansas. Head to Amazon.com for your copy.

I was happy to be beside her in some of our best memories--family vacations--especially the one where we played cards non-stop in the back of the borrowed camper while driving through Yellowstone.
