As some of you may know, many Wal-Marts will let you park your RV overnight for no charge. You are also free to purchase their wares as you trek through their store on the way to and from their bathrooms.

Alyssa and Bev and I spent a night in the parking lot of the Bakersfield Wal-Mart on our way to Joshua Tree. Bev is a seasoned RV traveler (we were riding in her Lazy Daze) and is not put off by camping in a parking lot. Alyssa and I, on the other hand, were excited about the prospect of Joshua Tree and not thrilled about the landscape offered by Wal-Mart.

But every day of this trip was special in some way, and our minds were blown even at Wal-Mart by the beauty of the biggest double rainbow I have ever seen in my life. This photograph, taken with a wide-angle lens from the window of the Lazy Daze, only hints at its magnificence.
